President Joe Biden's re-election campaign and the Democratic National Committee said Saturday that they raised more than $90 million in March and ended the year's first quarter with $192 million-plus in cash on hand, further stretching their money advantage over Donald Trump and the Republicans.

The Biden campaign and its affiliated entities reported collecting $187 million from January through March and said that 96% per cent of all donations were less than $200.

That total was bolstered by the $26 million-plus that Biden reported raising from a March 28 event at Radio City Music Hall in Manhattan that featured former Presidents Barack Obama and Bill Clinton. Trump's campaign, meanwhile, said it raised $50.5 million from an event Saturday with major donors at the Florida home of billionaire investor John Paulson, setting a single-event fundraising record.

Biden's campaign says the pace of donations has allowed it to undertake major digital and television advertising campaigns in key states and to work with the DNC and state parties to better mobilise would-be supporters before the November election.

The campaign said the $192 million-plus as of March 31 was the highest total ever by any Democratic candidate. About 1.6 million people have donated to the campaign since Biden announced in April 2023 that he was seeking a second term. The campaign raised more than $10 million in the 24 hours after the president's State of the Union speech in early March.

“The money we are raising is historic, and it's going to the critical work of building a winning operation, focused solely on the voters who will decide this election -– offices across the country, staff in our battleground states, and a paid media program meeting voters where they are,” Biden campaign manager Julie Chavez Rodriguez said in a statement. She scoffed at “Trump's cash-strapped operation that is funneling the limited and billionaire-reliant funds it has to pay off his various legal fees.”

Trump is facing four separate criminal indictments. He and the Republican National Committee reported raising $65.5 million in March and having $93.1 million on hand. As the incumbent in 2020, Trump had a huge campaign treasury when he lost to Biden.

Trump campaign officials have said they do not expect to raise as much as the Democrats, but will have the money they need. The Biden campaign says its strong fundraising shows enthusiasm for the president, defying his low approval ratings and polls showing that most voters would rather not see a 2020 rematch.
