President Donald Trump has hailed the “great American comeback” in a speech to Congress that exposed sharp divisions at the top of US politics.
At his annual State of the Union address, Mr Trump set out his case for another four years in office.
He was speaking on the eve of his expected acquittal on corruption charges in his impeachment trial.
At one point the Democratic 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.
His trial in the upper chamber, the Senate, culminates on Wednesday but with Republicans in charge there he is all but certain to be cleared and escape being thrown out of office.
Mr Trump did not mention impeachment at all in his speech although he did jab at Democrats.
Republican lawmakers chanted “four more years” as Mr Trump prepared to speak, urging him on for November’s White House election.
The State of the Union address is a speech delivered by the president to Congress towards the beginning of each calendar year in office.
It is usually used as a chance to report on the condition of the nation, but also allows the president to outline a legislative agenda and national priorities.
Mrs Pelosi has been one of the president’s fiercest critics – she was the one who first launched formal impeachment efforts last year. Mr Trump has frequently taunted her as “Crazy Nancy”.
It was the first time the two had come face-to-face since she stormed out of a White House meeting four months ago.
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”.
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.
