Biden faces donor pressure as he digs in on re-election bid

President Joe Biden is facing pressure from some major Democratic donors as he faces a critical few days in his campaign for re-election.

A number of donors are publicly warning they will withhold funds unless Mr Biden is replaced as the party's candidate following his disastrous debate performance last week.

Friday is a big day for the president as he seeks to shore up his candidacy with a rare primetime TV interview and a rally in Wisconsin. Pressure on Mr Biden, 81, to step aside has grown following a debate marked by several instances where he lost his train of thought.

While he admitted that he "screwed up" that night, he has vowed to stay on as his party's standard-bearer taking on Donald Trump in the November presidential election. Scrutiny on his public appearances has markedly increased since the debate.

In a White House speech to military families on Thursday to mark 4 July Independence Day, he stumbled over his words when referring to Trump as "one of our colleagues, the former president".
