Joe Biden vows to ‘complete the job’ in closely watched press conference

Joe Biden vowed to stay in the US presidential race and defended his fitness for office in a high-stakes press conference on Thursday, but failed to halt more defections from Democratic lawmakers urging him to drop his re-election campaign.

Speaking at the end of the Nato summit in Washington, Biden said he was best qualified to defeat Donald Trump in November and still had time to recover from what he called the “stupid mistake” of his damaging debate performance two weeks ago.
