Trump avoided the subject of his impeachment drama in a pugnacious 80-minute speech, but the raw wounds from the battle were evident with fellow Republicans giving him standing ovations while rival Democrats for the most part remained seated.
The Republican-led Senate was expected to acquit him of charges he abused his powers and obstructed Congress during a vote beginning at 4 p.m.
EST on Wednesday.
Seeing Pelosi, the U.S. House of Representatives speaker, for the first time since she stormed out of a White House meeting four months ago, Trump declined to shake her outstretched hand as he gave her a paper copy of his remarks before starting to speak.
Despite having not spoken to Trump since their last meeting, Pelosi appeared to be taken aback.
She avoided citing the customary "high privilege and distinct honor" that usually accompanies the speaker's introduction of the president to Congress.
"Members of Congress, the President of the United States" was all she said in introducing Trump.
When his speech ended, Pelosi stood and tore up her copy of the remarks he had handed her, later telling reporters it was "the courteous thing to do, considering the alternative."
