The US House Judiciary Committee has postponed a vote on two impeachment charges against President Donald Trump to later on Friday.
The decision was taken by Democratic committee chairman Jerry Nadler, after two days of acrimonious debate.
Republicans attempted to stall the process, which they described as an illegitimate attack on Mr Trump.
The Democrat-run committee is expected to approve the charges of abuse of power and obstruction of Congress.
A full vote by the Democratic-run House would then follow next week, likely making Mr Trump the third US president to be impeached.
But the Senate, controlled by the president’s fellow Republicans, is not expected to remove him from office.
Mr Trump denies any wrongdoing. “No crime!” he wrote on Twitter early on Thursday.
Mr Nadler said the vote would not take place until 10:00 local time (15:00 GMT) on Friday. There are 41 members – 24 Democrats and 17 Republicans – on the judicial committee. They are expected to vote according to party affiliation.
What do the articles of impeachment say?
Mr Trump is accused of trying to force Ukraine to launch a corruption investigation into his political rival Joe Biden, a leading Democratic presidential contender; and of obstructing Congress by stonewalling the House investigation.
Leading Democrats agreed the language across nine pages detailing the charges against the president, which say that Mr Trump “betrayed the nation” by acting “corruptly”.
What was said in the debate?
Day two of the judiciary committee’s marathon session saw Jim Jordan, an Ohio Republican, attempt to have the first impeachment charge against Mr Trump removed. Mr Jordan’s amendment was rejected after hours of debate on a 23-17, party-line vote.
“This notion of abuse of power is the lowest of low-energy impeachment theories,” said Matt Gaetz, a Florida Republican and staunch defender of the president whose own proposed amendment was also defeated.
Democrat committee members rebuked Republicans for their fealty to Mr Trump.
“Is any one of my colleagues willing to say that it is ever OK for a president of the United States of America to invite foreign interference in our elections?” asked Pramila Jayapal, a Washington Democrat.
Mr Nadler’s decision late on Thursday to adjourn the vote enraged the Republican members.
