The Federal Reserve’s inspector general is reviewing the Trump administration’s attempts to lay off nearly all Consumer Financial Protection Bureau employees and cancel the agency’s contracts, CNBC has learned.

The inspector general’s office told Sen. Elizabeth Warren, D-Mass., and Sen. Andy Kim, D-N.J., that it was taking up their request to investigate the moves of the consumer agency’s new leadership, according to a June 6 letter seen by CNBC.

“We had already initiated work to review workforce reductions at the CFPB” in response to an earlier request from lawmakers, acting Inspector General Fred Gibson said in the letter. “We are expanding that work to include the CFPB’s canceled contracts.”

The letter confirms that key oversight arms of the U.S. government are now examining the whirlwind of activity at the bureau after Trump’s acting CFPB head Russell Vought took over in February. Vought told employees to halt work, while he and operatives from Elon Musk’s Department of Government Efficiency sought to lay off most of the agency’s staff and end contracts with external providers.

That prompted Warren and Kim to ask the Fed inspector general and the Government Accountability Office to review the legality of Vought’s actions and the extent to which they hindered the CFPB’s mission. The GAO told the lawmakers in April that it would examine the matter.
