Democratic National Committee member Alan Clendenin of Florida said on Sunday US president Joe Biden should step aside as the Democratic Party's presidential candidate and allow vice president Kamala Harris to take over.
"Joe Biden will be remembered by historians as one of the finest presidents in American history, but this election is about the next four years, not the last three and a half," Mr Clendenin said in a statement on social media platform X.
Mr Biden was attending a black church and rallying with union members on Sunday in the critical swing state of Pennsylvania, trying to project enough strength for his re-election campaign to quell a growing clamour from within in his own party for him to bow out of the race.
The pair of appearances come after Mr Biden joined a Saturday call with campaign surrogates, and reiterated that he has no plans to step aside, while urging unity among top Democrats.
Five Democratic lawmakers have called on him to abandon his re-election bid ahead of November, and more could do so in coming days, as Congress reconvenes.
Meeting in person will give congressional Democrats a chance to discuss concerns about Mr Biden’s ability to withstand the remaining four months of the campaign — not to mention four more years in the White House — and true prospects of beating former Republican former president Donald Trump.
