Democrats are charging Donald Trump with “incitement of insurrection” as part of impeachment proceedings following last week’s US Capitol riot – with the FBI warning that armed protests are planned nationwide ahead of Joe Biden’s inauguration.
Opposition politicians have filed one article of impeachment which states Mr Trump made statements at a rally of his supporters that “encouraged and foreseeably resulted in” last week’s violence.
Republicans have blocked an attempt to immediately consider a resolution asking the vice president, Mike Pence, to invoke the 25th Amendment and remove Mr Trump from office.
Proceedings in the House of Representatives have been adjourned until Tuesday, when a vote on that resolution is expected.
Mr Pence is believed to be against forcing his boss from power, so a vote on the impeachment could happen on Wednesday, and needs a simple majority to pass.
If it is voted through, it would move to the Senate for trial with senators acting as jurors and voting on whether to acquit or convict Mr Trump.
