Rohit Chopra was one of the more important regulators from the previous Democratic administration who was still on the job since President Trump took office on Jan. 20.

Rohit Chopra, head of the top U.S. watchdog agency for consumer finance, announced early Saturday his time in office had ended after President Donald Trump fired him overnight, according to a letter Chopra posted online and a person familiar with the situation.

Chopra, a Sen. Elizabeth Warren protege, was a surprising holdover from the Biden administration, given that many appointees resigned as Trump entered office.
