That's it for our live blog coverage of the State of the Union. Cue another standing ovation.

There is no shortage of people mocking Trump's plea for greater unity tonight.

In one of the most poignant moments of the speech, the parents of Otto Warmbier received a standing ovation. Their son died after being imprisoned in North Korea for stealing a poster.

Trump referred to them as he spoke about destroying the North Korean regime.

Some reactions from the US punditry:

CNN commentator Van Jones: "He was selling sweet tasting candy with poison in it."

Sean Hannity, Fox News host and Trump friend: "Best speech ever."

New York Times' Peter Baker: "The challenge for Trump is that even as he sells the economy with the fervour of a real estate developer, he has not been able to sell himself."

And the front page of tomorrow's New York Daily News...

Trump stayed largely on script, no small feat for a president who is notorious for going off script and inserting his own hyperboles, insults and mystifying non-sequiturs that tend to quickly grab the headlines.

Tonight, he successfully followed the teleprompter.

The replies from various Democrat representatives are rolling in.

Independent senator Bernie Sanders is ripping into Trump on his live stream. The infrastructure idea is "old", his claim to be helping the drugs crisis is ridiculous considering he is cutting Medicaid and his pleas for unity are simply duplicitous.

"The American people do not want a president who is compulsively dishonest, who is a bully, who actively represents the interests of the billionaire class, who is anti-science and who is trying to divide us up based on the colour of our skin... our religion, our agenda or our sexual orentiation."

And after less than 10 minutes, Joe Kennedy's official reply speech is done. It was a relatively dark speech that deplored the divisiveness gripping America and reinforced support for those communities being targeted by the Trump administration.

For all the talk of bipartisanship before the speech, neither Kennedy nor Trump seemed to want to extend the olive branch.

Several commentators, however, say Kennedy's speech has set the scene for him to make a presidential run down the track.

Joe Kennedy has delivered a few lines in his speech in Spanish then says he promises to fight for Dreamers and immigrants.

"The American promise is being broken," he says. "By an Administration that callously appraises our worthiness and decides who makes the cut and who can be bargained away. They are turning American life into a zero-sum game. Where for one to win, another must lose."

He has urged people to have faith and to fight for the state of the union.

Now Congressman Joe Kennedy is giving the official Democrat response from Fall River in Massachussetts.

He begins by saying it is a town "built by immigrants".

"We all feel the fractured fault-lines across our country. We hear the voices of Americans who are forgotten and feel forsaken."

In the 5159-word speech, Trump covered a huge amount of ground.

He moved from spruiking his tax cuts to talking about the price of prescription drugs, the country's failing infrastructure, the war on drugs and gangs, the opioid crisis, immigration, cutting aid to countries that don't support America and defeating North Korea.

There were a whopping 115 applause lines.

While the White House has promised that it would be a bipartisan speech calling for unity, commentators have questioned if they got that at all.

It was not an "olive branch," conservative Fox News commentator Juan Williams said.

"He took credit for everything. To me, it was bellicose and I'm just struck by it... He was going tonight to come right into this and offer some healing and some positive reinforcement. I think he gave Democrats every reason to sit on their hands and walk out early."

Trump concluded his first State of the Union:

"As long as we are proud of who we are, and what we are fighting for, there is nothing we cannot achieve."

"As long as we have confidence in our values, faith in our citizens, and trust in our God, we will not fail.

"Our families will thrive.

"Our people will prosper.

"And our Nation will forever be safe and strong and proud and mighty and free.

"Thank you, and God bless America."

Representative Joe Kennedy - tapped to give the Democratic response - offers a little in-speech levity.

...And people in the audience chant 'U-S-A! U-S-A!'

Keen watchers will have picked up on Trump's sneaky use of the phrase "Americans are dreamers", perhaps a deliberate nod to the ongoing debate over the so-called Dreamers or undocumented children brought to America by their parents.

And another from the Washington Post on Trump's claim that Chrysler is moving its facilities back to America because the economy is booming.

"Trump's timeline is mixed up. Fiat Chrysler is investing $1 billion in a factory in Michigan, but that plan was in motion before Trump's election in 2016, according to Sergio Marchionne, the Fiat Chrysler chief executive. Marchionne specifically credited talks with the United Auto Workers in 2015, not Trump."

Here are the various guests Trump has invited and is paying tribute to throughout his speech.

They include the parents of children killed by the MS-13 gang, a couple who adopted the baby of an opioid addict, a young boy who started an initiative to put flags on veterans' graves and a hard-working welder who just bought his first home.

"As we rebuild America's strength and confidence at home, we are also restoring our strength and standing abroad."

"Around the world, we face rogue regimes, terrorist groups, and rivals like China and Russia, that challenge our interests, our economy and our values."

"In confronting these horrible dangers, we know that weakness is the surest path to conflict and unmatched power is the surest means to our true and great defence. "

Then Trump discusses modernising the US's nuclear arsenal.

After laying out a four-pillar plan for immigration reform, saying its pitched for maximum bi-partisan support, Trump unveils a shift away from the existing system that allows in "virtually unlimited numbers of distant relatives" to the country.

"It's time to begin moving toward a merit-based immigration system, one that admits people who are skilled, who want to work, who will contribute to our society and who will love and respect our country."

Curiously, House Speaker Paul Ryan, who has almost spent more time on his feet than his seat during the speech so far, declined to give a standing ovation when Trump said he will support paid parental leave.
