Donald Trump’s support from Republicans on Capitol Hill was draining away on Tuesday night as a flurry of the party’s congressmen announced they would vote for impeachment.
Four Republican members of the US House of Representatives went public with their decision to impeach, condemning his speech whipping up a crowd of supporters before some stormed the US Capitol.
Those backing impeachment included Liz Cheney, the third most senior House Republican and the daughter of former US vice president Dick Cheney, who gave a brutal assessment of Mr Trump.
“There has never been a greater betrayal by a President of the United States of his office and his oath to the Constitution”, Ms Cheney said of Mr Trump’s incitement of the mob.
Mike Pence, the US vice president, on Tuesday announced that he would not be invoking the 25th Amendment, a mechanism that allows a majority of the cabinet to remove a president who cannot fulfil his duties.
Mr Pence said in a letter to Nancy Pelosi, the Democratic House speaker who backed a resolution calling for the move, that it would “set a terrible precedent”.
