Investigations
After he assumed the presidency, Trump was the subject of increasing Justice Department and congressional scrutiny, with investigations covering his election campaign, transition, and inauguration, actions taken during his presidency, along with his private businesses, personal taxes, and charitable foundation.[525] There were 30 investigations of Trump, including ten federal criminal investigations, eight state and local investigations, and twelve congressional investigations.[526]
In April 2019, the House Oversight Committee issued subpoenas seeking financial details from Trump's banks, Deutsche Bank and Capital One, and his accounting firm, Mazars USA. Trump then sued the banks, Mazars, and committee chair Elijah Cummings to prevent the disclosures.[527] In May, DC District Court judge Amit Mehta ruled that Mazars must comply with the subpoena,[528] and judge Edgardo Ramos of the Southern District Court of New York ruled that the banks must also comply.[529][530] Trump's attorneys appealed the rulings.[531] In September 2022, the committee and Trump agreed to a settlement about Mazars, and the accounting firm began turning over documents.
