Thank you for joining us tonight.

We will leave you with a neat comparison of Trump then and now.

This was not the president's first address to a joint session of Congress. In 2017 he spoke just after winning the election, but technically it was not a State of the Union.

Here are the words he used then and now, composed by the BBC's Franz Strasser, external.

Mr Trump’s poll numbers have lagged below the mark one would expect a leader presiding over a prosperous economy. The president, in his speech, set about trying to change that.

When it came to policy, Mr Trump offered some bipartisan suggestions with few details, such as addressing high prescription drug prices, infrastructure investment, job training and prison reform.

Where the president lingered, however, was on topics that will prove as divisive as ever. The paeans to patriotism and traditional values will be viewed by Democrats as a rekindling of culture wars.

He spoke of standing for the national anthem, and Democrats sat stony-faced.

The president’s pledge to offer an open hand on immigration negotiations was surrounded by extended passages about immigrant crime and a veiled swipe that “Americans are dreamers, too”.

The president’s speech had a softer touch. The language was smooth. The edge, however, was still as sharp.

After suffering its biggest one-day drop in eight months, the US stock market is now steadily ticking back up.

S&P 500 E-mini futures climbed 0.28% as Trump took the podium.

It's not clear exactly what caused the drop, but analysts blame the healthcare market and the coming raise in interest rates.

Natalie Sherman, from BBC Business in New York, says its too early to know for sure if an econmic downturn has arrived.

"Wall Street may be taking a breather, only to rally higher, but anxieties are likely to continue," she writes.

US stocks fall for second consecutive day

BBC Mundo is analysing the key points of Trump’s First State of the Union Address from the BBC News bureau in Miami (in Spanish).

BBC Mundo journalists Liliet Heredero, external and Luis Fajardo, external will be answering your questions in their Facebook live feed.

"It would be easy to dismiss the past year as chaos. Partisanship. Politics. But it’s far, far bigger than that.

"This administration isn’t just targeting the laws that protect us - they are targeting the very idea that we are all worthy of protection."

Kennedy adds a few lines in Spanish, as he approaches the end of his speech.

"You are a part of our story. We will fight for you. We will not walk away," he adds.

Congressman Joe Kennedy is now giving the Democratic rebuttal.

He is speaking from an autoshop in his home state of Massachusetts.

"The people here are tough. They fight for each other. They pull for their city", he says speaking from the town of Falls River.

Virginia Senator Tim Kaine, who ran as Hillary Clinton's running mate in the 2016 election, seemed unimpressed by Trump's speech.

Reality Check

"I'm proud to report that the coalition to defeat ISIS has liberated almost 100% of the territory once held by these killers in Iraq and Syria," President Trump says.

On 1 January, Lt Gen Paul E Funk II, commanding general of the coalition, said "more than 98 percent of the land, external once claimed by the terrorist group has been returned to the people".

As President Trump acknowledges, the US is not the only country fighting against the Islamic State group. The coalition's website lists 74 partners, external, from Albania to the UAE.

It's also important to note that IS was losing territory before President Trump took office.

The coalition was formed in September 2014. Last January, President Obama said, external IS had lost 40% of its territory in Iraq, and 10% in Syria.

Twitter just announced that President Trump's State of the Union is the most tweeted ever with 4.5m tweets. (It surpassed previous record of 3m in 2017.)

With chants of "USA, USA!" Trump's speech comes to a conclusion.

He is now leaving the chamber, shaking hands with lawmakers on his way.

He stopped for a moment to put a hand on the shoulder of Senate Majority Leader Mitch McConnell.

Other Republicans are rushing past each other, seeking an opportunity to congratulate the president.

One of the most powerful moments of the night as Trump told the story of Otto Warmbier, and honoured his parents and siblings who were in the audience.

"Otto Warmbier was a hardworking student at the University of Virginia. On his way to study abroad in Asia, Otto joined a tour to North Korea. At its conclusion, this wonderful young man was arrested and charged with crimes against the state.

"After a shameful trial, the dictatorship sentenced Otto to 15 years of hard labour, before returning him to America last June - horribly injured and on the verge of death. He passed away just days after his return."

Trump calls out a former North Korean prisoner in the chamber tonight, who brought with him the crutches he used to escape the so-called Hermit Kingdom.

Ji Seong-ho was a starving child when he escaped North Korea. During his escape he was struck by a train and had to have multiple amputations "without anything to dull the pain," says Trump.

Seong-ho's father was caught escaping and tortured to death. He now lives in Seoul, and broadcasts messages that "the regime fears the most - the truth".

The BBC's Anthony Zurcher is answering your questions in our live feed of Trump's speech.

"Last year, I also pledged that we would work with our allies to extinguish ISIS from the face of the Earth," says Trump.

He is now vowing to send captured terrorists to Guantanamo Bay detention centre in Cuba.

To a mixture of boos and applause, Trump announced: "I just signed an order directing Secretary Mattis, who's doing a great job, thank you... to re-examine our military detention policy and to keep open the detention facilities at Guantánamo Bay."

Some Democrats are wearing orange ribbons to show their opposition to Trump policies which have led to increased deportations of immigrants who entered the US illegally.

"We can show the world this is happening," said Cindy Garcia, whose husband Jorge was deported after more than 30 years in the US, external.

Other lawmakers are wearing purple ribbons in an effort to raise awareness of the US opioid epidemic.
