President Donald Trump has hailed the “great American comeback” in a speech to Congress on the eve of his expected acquittal in his impeachment trial.
At his annual State of the Union address, Mr Trump set out his case for another four years in office.
The president refrained from lashing out directly at the lawmakers who have attempted to remove him from office, though he did jab at Democrats.
House Speaker Nancy Pelosi ripped up a copy of his speech behind him.
The Republican president delivered Tuesday night’s nationally televised speech in the Democratic-controlled House of Representatives, where he was impeached in December.
On the other side of the Capitol, the Republican-led Senate is all but certain on Wednesday to clear the president of corruption charges in a party-line vote.
Republican lawmakers chanted “four more years” as Mr Trump prepared to speak, urging him on for November’s White House election.
How did Trump and Pelosi clash?
Before Mr Trump began speaking at the podium in the well of the House, he appeared to snub the outstretched hand of Mrs Pelosi, America’s most powerful elected Democrat.
The House speaker, critics noticed, skipped the traditional introduction welcoming the president as a “distinct honour”.
It was the first time Mr Trump had come face to face with his implacable political foe since she stormed out of a White House meeting four months ago.
When the president accused Democrats of planning to force American taxpayers to provide unlimited free healthcare to undocumented immigrants, Mrs Pelosi was observed twice mouthing: “Not true.”
She stunned onlookers by shredding a copy of the president’s remarks as he concluded.
Mrs Pelosi told reporters afterwards her gesture was “the courteous thing to do, considering the alternatives”.
She did rise to applaud the president more than once, including when he promoted his pet project of infrastructure investment, a possible area of bipartisan co-operation.
What else did the president say?
Mr Trump struck an upbeat note in a speech lasting one hour and 18 minutes that contrasted sharply with his lament of “American carnage” in his 2017 inaugural presidential address.
In an implicit rebuke to his predecessor Barack Obama, the president told his audience: “In just three short years, we have shattered the mentality of American decline and we have rejected the downsizing of America’s destiny.
“We are moving forward at a pace that was unimaginable just a short time ago, and we are never going back!”
Mr Trump repeatedly swiped at Democrats, including left-wing candidates such as Bernie Sanders, who are vying to challenge him for the presidency.
“We will never let socialism destroy American healthcare!” said the president, whose critics point out that he has not put forward a healthcare plan of his own.
Who were the guests?
The president invited several special guests to the address, including Venezuelan opposition leader Juan Guaidó, military veterans and the brother of a man killed by an undocumented immigrant.
In a move certain to infuriate liberal critics, Mr Trump announced he would award the Presidential Medal of Freedom, America’s highest civilian honour, to firebrand conservative radio host Rush Limbaugh, who revealed this week he has lung cancer.
First Lady Melania Trump bestowed the honour on an emotional Mr Limbaugh as the president spoke.
A protester was escorted from the chamber while Mr Trump defended gun rights. It was Fred Guttenberg, the father of Jaime Guttenberg, a student killed in a mass school shooting at Parkland, Florida, in February 2018.
Mr Guttenberg was a guest of Mrs Pelosi.
