Former President Donald Trump's political action committee spent about three-quarters of the cash it collected last month on his mounting legal expenses — for a total of nearly $3.7 million, according to a new report.

The Save America PAC also ended March owing $886,000 in attorney fees, mostly to the firm that represented Trump in the New York civil fraud case that resulted in a judgment against him of $355 million, plus interest, CNN said, citing a Saturday night filing with the Federal Election Commmission.

Save America is a so-called leadership PAC, which under federal law can be established by a candidate or elected official to support other people seeking public office.

The PAC reportedly paid a combined $1.14 million in March to the law firms of Todd Blanche and Susan Necheles, who represent Trump in the criminal "hush money" trial in Manhattan, where jurors are scheduled to hear opening statements on Monday.

Save America also received a $5 million infusion from MAGA Inc., a super PAC that backs the presumptive presidential nominee and which has received $60 million from his leadership PAC, according to CNN.

The transfer means MAGA Inc. has returned $57.25 million to Save America and is closing in on the maximum $60 million it can refund, according to the network.

Trump reportedly plans to replace that funding source through a recent deal with the Republican National Committee and dozens of state GOP committees, whirch are giving his PAC $5,000 from each of their big-dollar donors.

Save America is first in line for that cash, CNN said, citing a fundraiser invitation it obtained.

Earlier this month, the first event held pursuant to the agreement raised more than $50.5 million, according to Trump's campaign.

Trump's main campaign account had $45.1 million on hand at the end of March, far behind the $85.5 in President Joe Biden's political war chest, CNN said.
