President Trump is now repeating his claim that Vice-President Mike Pence, who is overseeing the certification of the electoral college vote later, can overturn the election.

"If Mike Pence does the right thing, we win the election," he says.

Pence, however, has no legal authority to declare President-elect Joe Biden's victory invalid. Read more from BBC Reality Check on that below.

Trump goes on to suggest that members of his party who are not voting to reject Biden's win today are "weak".

The outcome of Georgia's twin run-off elections decides the balance of power in the US Senate. We asked members of our voter panel in Georgia what motivated them when casting their ballots.

Steven Burkhart, 53, an independent voter from Atlanta who owns a small business, said "the idea of the Democrats controlling the government is very frightening to me".

He disagrees with the Democrats' police reform policies and says the party has a "mentality" of wealth redistribution - "and I just don't think that's very conducive to a good economy".

Robert Patillo, 36, a Democrat from Atlanta who sent in his absentee ballot on the first day of early voting, says his party has a platform of "reality versus the far-right-wing conspiracy theories" of Republicans.

"If you look at campaign ads, the Republican candidates are saying we need to save Western civilisation and fight back against socialism, communism and Marxism, but they never talk about real issues that impact Georgians.

"Neither of them has a plan to address the coronavirus or an economic platform that would help the average person."

"We will never concede," Trump continues, falsely claiming that he actually won by a larger margin against Biden than he did in 2016 against Hillary Clinton.

The crowd is now chanting "fight for Trump" as he tells them their voice will not be silenced.

The president has continually questioned the election results without any evidence. Here's a fact-check on what he said at the weekend.

Trump is now addressing supporters who are gathering in Washington DC.

He begins by saying the crowd, which numbers in the thousands, "came from all over the world" and that the media is not showing the real size of the crowd.

Once the seemingly inevitable occurs and Democrat Jon Ossoff is formally declared the winner of his Senate race, the Republican defeat in the 2020 election cycle will be complete.

The party will have lost control of the presidency and both chambers of Congress, and the blame-assigning will quickly follow.

Donald Trump and his supporters, when they're not lobbing accusations of election fraud, will argue that the Republican losses are because the party's leadership in the state, from Governor Kemp on down, was insufficiently loyal to the president.

Trump's critics within the party - and their numbers will grow - will hold the president responsible for squandering a probable victory by attacking Georgia Republicans and depressing conservative turnout with his unsubstantiated claims of voting illegalities.

One thing is certain, however. As was the case in the 2018 congressional mid-term elections, Republicans are finding it difficult to win elections without Trump on the ballot. Their coalition - when it doesn't have the white working-class and rural turnout boost the outgoing president elicits - is underpowered.

That is a serious problem for Republicans to address, given the fact that Trump's name may never appear on a ballot again.

President-elect Joe Biden has congratulated Democrat Rev Raphael Warnock on his "ground-breaking win" in one of two Senate elections in Georgia.

"I am hopeful that when the count is complete, Jon Ossoff will also be victorious," he said in a statement on his website, external.

Biden said that voters in Georgia had "delivered a resounding message" that they "want action on the crises we face and they want it right now".

The president-elect, whose win in November's presidential election is due to be certified later on Wednesday, said it was "time to turn the page", adding that voters wanted both "action and unity" and that he was "more optimistic than I ever have been that we can deliver both".

Warnock is projected to have won his seat, and fellow Democrat Ossoff leads narrowly in the other. If both candidates win, the Democrats will take control of the Senate - and in doing so, all of Congress as they already control the House of Representatives.

Democrat Jon Ossoff is leading Republican David Perdue by around 17,000 votes.

In a news conference, Georgia election official Gabriel Sterling said that Ossoff will probably get enough votes to avoid an automatic recount.

"Jon Ossoff will likely have a margin outside of the .5% to avoid a recount," said Sterling.

He also referred to Ossoff, who is yet to be declared the winner, as "Senator to be, probably, Ossoff".

President Trump is expected to address his thousands of supporters who have descended on Washington to protest his election loss and to pressure Republicans to attempt to overturn the 2020 presidential vote.

So far, the crowd has been treated to speeches by Trump's two sons, his lawyer Rudy Giuliani and preacher Paula White.

There's an intriguing side to the Warnock v Loeffler race in Georgia that you might not have heard about.

Republican Kelly Loeffler - currently the richest member of the US Senate - is also co-owner of her state's women's pro-basketball team, the WNBA's Atlanta Dream.

The problem: they don't like her very much.

Over the summer, when Loeffler called for the WNBA to reject "divisive political movements" like Black Lives Matter, Dream players (and others in the league) called for her removal as team owner and began to sport "VOTE WARNOCK" jerseys at their games, making pretty clear their support for her Democratic opponent.

Their activism raised over $200K (£150,000) in just three days for Raphael Warnock - according to his campaign - and boosted his visibility in the early days of his candidacy.

As news broke overnight of Warnock's projected win over Loeffler, NBA superstar - and vocal anti-Trump activist - Lebron James took to his Twitter with an offer: "Think I'm gone put together an ownership group for The Dream. Whose in?"

Away from Georgia, the US Senate and House of Representatives are convening today in Washington to certify the results of the November 2020 presidential election.

What is normally a ceremonial affair is going to be a bitter political fight as a group of President Trump's Republican allies heed his call to object to the results in a last-ditch bid that is expected to fail.

Here's what we can expect:

• The joint session overseen by Vice-President Mike Pence begins at 13:00EST (18:00GMT) but could go on for hours
• Dozens of Republican lawmakers say they will object to the certification of the Electoral College vote, which Biden won by 306 to Trump's 232
• Pence will begin by asking the "teller" from the state of Alabama (which is alphabetically the first of 50 US states) to read out the number of Electoral College votes received by each candidate
• If an objection is raised by both a member of the Senate and the House, the two chambers are each allocated two hours per objection to debate the matter before voting on whether to uphold it or not
• For a state's electoral votes to be tossed out, majorities in both the House and Senate must vote to do so. With the House in Democratic control and many Republican senators refusing to abide by Trump's wishes, this won't happen
• But all eyes will be on what Vice-President Mike Pence does - Trump has pressured him to reject the results even though he has no legal authority to do so

Can rebel Republicans overturn the election?

Weeks after President-elect Joe Biden was declared winner of November's election, there remains a deep mistrust of the electoral process among many ardent supporters of Donald Trump. It reflects a broader sentiment among conservatives, one that has profound implications for the nation and its institutions.

Standing on Main Street, Dillard Ungeheuer, 73, was scraping cow manure off his shoes, left over from a visit to a cattle feed lot, and seemed testy. When it came to the ballots, he was emphatic - many were fake.

"I'm not going to argue with nobody about it," he said, voice rising. "I believe what I'm saying is factual."

"No, I don't have much faith in government at all," he added.

Trump's efforts to have the election results overturned in the courts have failed. Later on Wednesday, the electoral votes from each state will be counted by Congress. Although some Republicans will challenge this certification of Biden's victory, it will not change the outcome.

But most Republican voters, in Kansas and elsewhere, either believe Trump won the election or they are not certain of the victor, polls suggest., external

Jackie Taylor, 59, publisher of the Linn County News in Pleasanton, said the election was stolen: "The whole thing is dirty. You've got a guy who got elected under dirty circumstances, and now he's president."

Rev Raphael Warnock, who is set to become the first black senator for the US state of Georgia, was for 15 years a pastor of a church that was at the spiritual heart of the civil rights movement.

In a speech streamed online as the Democrat moved ahead of his Republican rival, Kelly Loeffler, Warnock said his "roots are planted deeply in Georgia's soil". Georgia was one of seven secessionist southern states that fought for the right to keep slaves during the US Civil War.

He talked of his "improbable journey" that began with his upbringing in public housing in Savannah, as the 11th of 12 children born to Jonathan, also a pastor, and Verene. His mother, he said, worked as a cotton-picker when she was younger.

"The other day, because this is America, the 82-year-old hands that used to pick somebody else's cotton went to the polls and picked her youngest son to be a United States senator," he said.

Republican Senator Mitt Romney was heckled by Trump supporters as he flew back to Washington DC from Utah yesterday.

People on the flight chanted "traitor" and called for him to resign after he earlier signed a statement saying he would vote to certify Democrat Joe Biden's win in the presidential election.

Romney was one of four Republican senators who in a joint statement on Sunday called on Congress to approve Biden's victory.

"The voters have spoken, and Congress must now fulfil its responsibility to certify the election results," said the statement, co-signed by Susan Collins, Lisa Murkowski and Bill Cassidy.

Since the 3 November vote, President Donald Trump has been making unsubstantiated allegations of widespread electoral fraud. US courts have rejected dozens of challenges to Biden's win.

Romney was also the only Republican to vote for Trump's impeachment last year.

Gabriel Sterling, a top Republican election official in Georgia, has just given an interview to CNN where he said that Democrats were likely to increase their lead as vote-counting continues.

Sterling said that the votes that remain to be counted come from Democratic strongholds and are therefore likely to be for Jon Ossoff and Raphael Warnock.

Sterling predicted that Ossoff would continue to hold his lead over Republican David Perdue in the coming hours, further boosting Democrats' hopes of capturing the Senate - and with it, control of all of Washington.

He added that Trump was "100% responsible" for Perdue losing his early lead over Ossoff in the polls, after he repeatedly questioned the validity of the electoral process.

"While [Trump] may inspire people on the Republican side, he really pisses off people on the Democratic side," said Sterling.

"When you can have a credible villain, that really helps the Democrats turn out their vote."

Several Trump supporters participating in a rally outside the White House in Washington on Tuesday night were arrested for gun crimes and fighting with police, according to local reports.

People taking part in the "Save America March" reject Trump's loss in the presidential election and are seeking to pressure Republican lawmakers to attempt to block the certification of Joe Biden's victory - an event which is happening on Capitol Hill later today.

Police in Washington DC reportedly arrested at least six people at Tuesday's rally. The alleged offences include possession of illegal weapons and firearms, and assault - including against a police officer.

Footage posted on social media showed clashes between Trump supporters - some of whom are members of far-right groups such as the Proud Boys - and police officers. One video appeared to show police using pepper spray on the crowd.

Thousands are gathering this morning for a second day of rallies - with President Trump expected to address the "Save America" group at 11:00 local time.

More than 98% of ballots from Georgia's 159 counties have now been counted, with many of the remaining votes coming from Atlanta suburbs which lean Democrat.

As things stand, Democrat Raphael Warnock is projected by US media organisations to have won his race with 50.6% of the vote. His opponent Republican Kelly Loeffler has 49.4% of the vote but has not yet conceded.

In the other race, Edison Research - which supplies election results to news organisations including the BBC - gives Democrat Jon Ossoff a lead of more than 16,000 votes. He has a 50.2% vote share compared to Republican Senator David Perdue's 49.8%. The race has not yet been called by the US networks.

An Ossoff win would split the Senate 50-50, but effectively give Democrats control of the chamber because soon-to-be VP Kamala Harris would be able to cast a tie-breaking vote as president of the Senate.

Although the result of the Ossoff-Perdue race is still too close to call - some Democrats aren't waiting for the final tally. Ossoff himself has already claimed victory.

Democratic Minority Leader and New York Senator Chuck Schumer, who is poised to become the Senate majority leader if Democrats take both seats, has already taken to using that title.

“As Majority Leader, President-elect Biden and Vice President-elect Harris will have a partner who is ready, willing and able to help achieve a forward-looking agenda and deliver help and bold change to the American people," he said in a statement minutes ago.

As we reported earlier, black voters are expected to have played a major role in determining the outcome of Georgia's run-offs.

But there's another factor in these elections - teenagers.

Since November's presidential election, more than 23,000 people will have turned 18 in Georgia, making them eligible to vote in this Senate race.

Valerie Ponomarev, who has just turned 18, told the BBC she was upset she couldn't cast a ballot in the recent presidential election.

"I did the math in my head and was short by a month as I was born in December," she says.

"I was mad at my mum that I hadn't been born sooner!"

She said she would vote for the Democrats in the Georgia run-offs, adding that a lot of younger people had shown support for Jon Ossoff, who at 33 would be the youngest senator elected in decades.

"I think the youth finally want representation in government because we're so often underrepresented and now that we have Jon Ossoff who is closer to our age," Valerie said.

Michael Guisto found himself in the same situation as Ponomarev in November. Missing out on that vote due to his age was painful, he said.

"It feels like a redemption," he said of this Senate race.

Eric Trump, the president's second son, has threatened to unseat Republicans that do not attempt to block the certification of Joe Biden as the 2020 presidential winner later today in the US Congress.

"I will personally work to defeat every single Republican Senator/Congressman who doesn’t stand up against this fraud - they will be primaried in their next election and they will lose," he tweeted on Tuesday night.

It came after he warned any lawmaker that did not attempt to thwart the vote that "their political career is over" because his father's political movement was "going nowhere".

Around 140 Republicans in the House of Representatives and at least 12 Republican senators say they will vote against Biden's certification. It's seen as a last-ditch effort that has no chance of succeeding because a majority in both chambers is required and Democrats control the House.

Many in Washington believe that Eric's older brother, Donald Jr, has presidential ambitions of his own.

In fact, before President Trump himself began mulling the idea of running for president again in 2024, Republicans had actively been talking about Don Jr taking the reins.

Black voters were vital to Joe Biden’s win in the state of Georgia in November’s presidential election.

In Tuesday’s run-off elections for the Senate, they were expected to be equally influential.

That’s because Georgia has a higher proportion of black voters than the average US state.

The state is around 52% non-Latino white and 33% black, according to 2019 census data.

Data analysed by the Pew Research Center shows the role of black voters is growing, accounting for almost half of the 1.9 million people who have joined the state's electorate since 2000.

Democratic rising star Stacey Abrams has been credited with increasing electoral participation among black voters in the state.

The former candidate to be the state's governor co-founded the voting rights group New Georgia Project with Rev Warnock, the Democrat who is now projected to be Georgia's first black senator.

Abrams has highlighted Georgia’s racial and ethnic diversification as a major driver behind Biden’s victory. Democrats hoped Rev Warnock would benefit from a similar trend in his run-off.

If confirmed, Ossoff’s victory would mean the Democrats would effectively control both houses of Congress - the Senate and the House of Representatives - as well as the presidency once Joe Biden is sworn in on 20 January.

Here's why:

With two new Democrats from Georgia, the Senate would be split 50-50 between the Republicans and the Democrats. In the event of a tie in a Senate vote, the vice-president has the casting vote, in his or her role as president of the Senate.

This means Vice-President-elect Kamala Harris may be a busy woman.
