Democrats and Republicans have clashed bitterly in an historic debate on the impeachment of President Bill Clinton over his handling of the Monica Lewinsky affair.
The marathon session is set to run until 2200 local time (0300 GMT) and members will reconvene on Saturday morning to vote on the motion.

Henry Hyde, chairman of the House judiciary committee, which drew up the four articles of impeachment against Mr Clinton, told members it was their obligation to defend the rule of law.
Four impeachment charges have been levelled at Mr Clinton. If any one is voted through, he will become only the second president to be impeached in the history of the United States.
But Democrats have repeatedly tried to avoid impeachment, preferring instead a censure motion on Mr Clinton.
Dick Gephardt, the Minority Leader of the House, reaffirmed this view to the House.
Meanwhile, the president's supporters outside Congress have been speaking in his defence.
Vice President Al Gore, speaking in a radio interview, said he was "fighting mad" about Republicans' conduct in the House debate.
In the House, sharp words and bitter sentiments have characterised proceedings.
Democrat Maxine Waters called the impeachment process a "Republican coup d'etat".
"I warn my colleagues, you will reap the bitter harvest of the unfair partisan seed you sow today," he said.
Democrat John Conyers said: "Impeachment was designed to rid this nation of traitors and tyrants, not attempts to cover up an extra-marital affair."
"As a matter of conscience, I must vote against impeachment, and I rue this day," he said.
But most in his party staunchly defended their efforts.
Sam Johnson, a former prisoner of war, said Mr Clinton's actions had "made a mockery of the people who had fought for this country and are fighting for this nation today".
Earlier, Democrats failed to further delay the already rescheduled debate because of US military action in Iraq. The session had been due to start on Thursday but was put back 24 hours because of events in the Gulf.
David Bonior, the Democrat Chief Whip, said: "We do not believe we should be here today while our men and women are fighting abroad."
With loyalties in the House fiercely split down party lines, it seems inevitable that at least one article will be approved by a simple-majority, thereby impeaching the president.
The BBC's Washington correspondent, Tom Carver, said the vote "looks pretty likely" to go against the president by a margin of eight to 10 votes.
However, Mr Clinton would not be immediately removed from office. Instead he would go for trial in the Senate - the upper house of government - where a two-thirds majority is needed to remove Mr Clinton.
