Biden Reports Major Cash Haul in March as Trump Looks to Catch Up

President Biden continued to build on his commanding financial advantage over former President Donald J. Trump, raising more than $90 million in March together with the Democratic Party and affiliated committees, his campaign said.

Mr. Biden, the party and their shared accounts now have $192 million on hand going into April, according to his campaign — more than double what Mr. Trump reported in his coffers this week. Since Mr. Biden began his re-election bid, 1.6 million Americans have donated money to him, his campaign said, reflecting a broad base of financial support.

These are “real investments that real Americans are making into this campaign,” said Rufus Gifford, the Biden campaign’s finance chair.

Mr. Gifford suggested that the campaign’s fund-raising strength was more important than polls that have consistently showed Mr. Biden trailing Mr. Trump.

“You can’t lie about the numbers,” Mr. Gifford said. “They’re not theoretical. It’s not a random poll that is just one moment in time.”

The president’s numbers were fueled by a $26 million haul from a fund-raiser at Radio City Music Hall in New York City that featured former Presidents Barack Obama and Bill Clinton. His campaign also said he raised $10 million in the 24 hours after his State of the Union address on March 7.

Mr. Trump has increased the pace of his own fund-raising, hosting wealthy donors at his Mar-a-Lago club in Palm Beach, Fla. His campaign said it and the Republican National Committee raised $65.6 million in March, Mr. Trump’s best fund-raising month so far. Trump campaign aides say they plan to out-raise Mr. Biden’s three-president bash with a major fund-raiser of their own on Saturday in Palm Beach.

But Mr. Biden’s prodigious March may take some of the wind out of Mr. Trump’s sails.

“We’ve got all the momentum now, and I think you’re going to continue to see it,” said Jeffrey Katzenberg, a co-chair of the Biden campaign. “These are spectacular outcomes for the campaign and a vote of confidence for the president and vice president.”

Of course, having the most money does not guarantee victory. And there are signs that Mr. Trump may continue to up his fund-raising.

March was the first month that Mr. Trump, now his party’s presumptive nominee, started to raise money in joint accounts with the R.N.C. Those accounts can accept far larger donations than Mr. Trump was allowed to in the primary.

Mr. Trump, the R.N.C. and their shared accounts roughly doubled their available cash on hand going into April. That figure now stands at $93.1 million, although it is still far less than Mr. Biden and the Democrats.
