Former President Donald J. Trump leaned heavily on major Republican donors in March as his campaign and the Republican Party sought to close the financial gap separating him from President Biden, new federal filings showed on Monday.
For much of the race, Mr. Trump has relied on small donors — in particular, those giving less than $200 online — to sustain his campaign. Most big donors steered clear.
But in recent weeks, as Mr. Trump finished trouncing his primary opponents and Mr. Biden and the Democrats gathered fund-raising steam, these donors have opened their checkbooks to the former president.
In the last two weeks of March alone, one committee backing Mr. Trump raised nearly $18 million, nearly all from six-figure contributions. Mr. Trump and the Republican Party finished the month with $93 million on hand between all their committees, his campaign has said, having raised more than $65 million in March.
Still, Republicans are lagging behind. In the first three months of the year, Mr. Biden and the Democratic Party together raised more than $187 million, his campaign has said, including $90 million in March, ending the month with $192 million on hand.
Mr. Trump’s campaign has not provided a full account of its first-quarter fund-raising. The two committees that filed on Monday reported raising nearly $90 million combined since January, but that does not include money raised directly by the campaign or the Republican National Committee.
