Among Trump's special guests are two key figures from a country more than 2,000 miles from Washington.

Venezuela's opposition leader Juan Guaidó is here, as well as Ivan Simonovis, the former police chief from Caracas, Venezuela's capital city, who was held in prison for almost 15 years under regimes of Hugo Chavez and current president President Nicolás Maduro.

"Maduro is an illegitimate ruler, a tyrant who brutalises his people," Trump said to a standing ovation. "Joining us in the gallery is the true and legitimate President of Venezuela, Juan Guaidó."

But why are they here? It may be domestically motivated: Trump has used Maduro and the conflict in Venezuela to stoke fears of socialism and, more specifically, the more progressive agendas of his Democratic opponents.

"Socialism destroys nations," Trump said earlier. "But always remember, freedom unifies the soul."

Trump calls on lawmakers "to pass legislation finally banning the late-term abortion of babies".

"Whether we are Republican, Democrat, or Independent, surely we must all agree that every human life is a sacred gift from God."

Abortion is a hot-button cultural issue that drives a wedge between Democrats and Republicans.

Last month, Trump made history by becoming the first sitting-president to attend the anti-abortion March for Life rally in Washington.

Trump has just asked First Lady Melania Trump to present the Presidential Medal of Freedom, the top civilian honour, to conservative radio host Rush Limbaugh.

"Rush Limbaugh: Thank you for your decades of tireless devotion to our country," he says.

He says it is "in recognition of all that you have done for our nation, the millions of people a day that you speak to and inspire, and all of the incredible work that you have done for charity".

The moment is significant, BBC correspondent Nick Bryant writes, as "few Americans over the decades have done more to make the conservative movement more radical or prepare the way for Donald Trump".

At the mention of Trump's talk of drug-pricing reforms, many Democrats stood up, holding up three fingers and shouting "HR 3" - a reference to the prescription drug bill that the Democrat-led house passed, which died in the Senate.

Trump's state of the union address up to now has been pretty standard fare - economic boasts, guest shout-outs, etc.

When the subject turned to healthcare, however, Trump went on attack against Democrats in the kind of direct way you don't normally see in these kind of speeches.

"Over 130 legislators in this chamber have endorsed legislation that would bankrupt our nation by providing free taxpayer-funded healthcare to millions of illegal aliens," says Trump, "forcing taxpayers to subsidise free care for anyone in the world who unlawfully crosses our borders."

As he spoke, Nancy Pelosi appeared to mouth "that's not true".

Mr Trump continues: "If forcing American taxpayers to provide unlimited free healthcare to illegal aliens sounds fair to you, then stand with the radical left. But if you believe that we should defend American patients and American seniors, then stand with me and pass legislation to prohibit free Government healthcare for illegal aliens!"

"A good life for American families also requires the most affordable, innovative, and high-quality healthcare system on Earth," says Trump.

He says that he has lowered the cost of healthcare premiums, which he says, are now 60% less expensive.

"I have also made an ironclad pledge to American families: We will always protect patients with pre-existing conditions - that is a guarantee.

"And we will always protect your Medicare and your Social Security."

The White House recently unveiled a plan to overhaul Medicaid - another social safety net that protects the poor.

The programme, branded as the “Healthy Adult Opportunity”, gives states the ability to withhold aid by creating work requirements, among other restrictions.

Almost all of the nation's top leaders have gathered in one room tonight for the State of Union: members of Congress, Supreme Court Justices and Trump's cabinet.

But not all of these leaders are present: one member of the cabinet the designated survivor does not attend the State of the Union. This always happens when the nation's top leaders are gathered at a single location.

He or she remains at a secure location to ensure continuity of government should a catastrophic event occur.

This year's designated survivor is Trump's Secretary of the Interior David Bernhardt.

It might be the most-talked-of moment of the night: Donald Trump snubbing the handshake of the leader of the House, Nancy Pelosi, who led impeachment proceedings against him. Watch it here:

Trump has just touted his controversial "America First" message, which some consider xenophobic and unwelcoming of America's immigrant communities.

"Members of Congress, we must never forget that the only victories that matter in Washington are victories that deliver for the American people.

"The people are the heart of our country, their dreams are the soul of our country, and their love is what powers and sustains our country.

"We must always remember that our job is to put America first."

An incumbent president’s election-year State of the Union address typically foreshadows the themes of the campaign to come. If that’s the case, Donald Trump’s speech makes clear he’s going to bet his presidency on the state of economy.

While growth figures for the past year have been modest, the president has presided over a record-long economic expansion. At the top of his speech – the portion that will have the most Americans watching – Trump rattled through the litany of facts and figures that support his contention that times are good and will stay that way if he’s given another four years in office.

He cited deregulation, tax cuts new trade agreements as his recipe for prosperity. In the campaign to come, expect him to make the case that a Democratic change of course will hit Americans voters in the place that hurts the most – their wallets.

Reality Check

The US President said that, after losing 60,000 factories under the previous two administrations, America had "now gained 12,000".

There were 54,000 fewer "private manufacturing establishments" (factories) at the end of 2016 compared with the start of 2001, according to the US Bureau of Labor Statistics.

In terms of the gains under Mr Trump's presidency, the most recent statistics for the second quarter of 2019 show there were roughly 12,000 more factories than when President Trump took office in 2017.

But most of these are small businesses, with fewer than five employees.

The number of factories overall started to increase in 2013, during the Obama administration.

Trump is cheering his creation of the Space Force, the newest branch of America's military.

"In the gallery tonight, we have one of the Space Force's youngest potential recruits: 13-year-old Iain Lanphier," says Trump.

"Iain has always dreamed of going to space... He aspires to go to the Air Force Academy, and then, he has his eye on the Space Force.

"As Iain says, 'most people look up at space, I want to look down on the world.'"

Iain is attending with his grandfather, Charles McGee, who was one of America's first black fighter pilots as a member of the Tuskegee Airmen.

Mr Trump has referred to Juan Guaidó, Venezuela's opposition leader, who has received a standing ovation. He is attending Trump's address, and is sitting right near Melania Trump.

Mr Trump called him "Mr President": the 36-year-old has been recognised as Venezuela's president by a number of heads of state, including the leaders of Brazil, Columbia and Peru as well as Donald Trump.

Tonight, he's being given a high-profile platform to stoke his efforts to oust President Nicolás Maduro.

Mr Trump referred there to the "groundbreaking new agreement" struck with China.

But it took a while to reach that point, and analysts say it's unlikely that the deal will produce gains sufficient to outweigh the losses already suffered.

Last month, the BBC's New York business reporter Natalie Sherman ran through who the main winners and losers were - you can read her analysis here.

"The fact is everybody wants to be where the action is, and the United States of America is, indeed, where the action is," Trump says, after touting America's "manufacturing might".

Reality Check

Donald Trump said "we have created seven million jobs" and that the unemployment rate was the lowest in half a century.

Since Mr Trump took office in January 2017, almost 6.7 million jobs have been added. Jobs have been added every month dating back to October 2010, when President Obama was in office.

The unemployment rate for December was 3.5%. This is the lowest level in 50 years - it last dropped to 3.5% in December 1969.

Reality Check

The US President said unemployment rates among African Americans had reached record lows.

The African-American unemployment rate hit 5.5% in September 2019, the lowest rate recorded since the US Labor Department started collecting these statistics, in 1972.

Since then, the unemployment rate rose slightly - to 5.9% in December.

But there is a disparity in weekly wages between racial groups. Black men on average earn 26% less than white men.

"This is a blue-collar boom," Trump says after saying that wages have risen, especially quickly for the lowest-earning Americans.

Trump made headlines even before taking he took the microphone.

Walking in to address the nation, the president did not shake the hand of top Democrat, Speaker of the House Nancy Pelosi.

The moment is unprecedented, says BBC correspondent Nick Bryant, who has covered American politics since the 1990s.

"Anything that Donald Trump says in the next hour or so will be overshadowed in the news tomorrow by his failure to shake the hand of the House Speaker Nancy Pelosi," Nick says.

"I've never seen that before."
