A fundraising group run by Donald Trump, who is facing four criminal trials as he seeks the U.S. presidency, stepped up spending on legal fees last month, further draining money from efforts to return him to the White House, financial disclosures showed on Wednesday.

In a filing to the Federal Election Commission, the group, known as Save America, detailed legal expense outlays totaling more than $5.5 million in February, the biggest single month of such spending since Trump, a Republican, formed the organization in 2020 following his defeat to Democrat Joe Biden in that year’s presidential election.

The spending marked an acceleration from the close to $3 million Save America reported spending on legal bills in January. The group, which raises money together with Trump’s election campaign but is legally separate, has now spent more than $55 million on legal bills since the start of 2023.
