Democratic presidential contender Joe Biden has called for US President Donald Trump’s impeachment for the first time.
Mr Biden refrained from making an outright plea for the move after he and his son featured prominently in the actions that led congressional Democrats to start impeachment proceedings.
During a campaign event in New Hampshire Mr Biden said President Trump had indicted himself and obstructed justice.
"In full view of the world and the American people, Donald Trump has violated his oath of office, betrayed this nation and committed impeachable acts,” Mr Biden said.
