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, director of the Consumer Financial Protection Bureau, posted a letter Saturday on X to President Donald Trump that he would no longer serve in the role.

Trump fired Rohit Chopra, the agency's director and a Biden appointee, over the weekend and installed Scott Bessent, a billionaire hedge fund manager who now serves as treasury secretary, as acting director. Bessent began freezing the agency's operations on Monday.
