Rep. Maxine Waters kicked off her chairmanship of the House Financial Services Committee by vowing that it will hold "many hearings" into bank conduct.

The California Democrat said those hearings would include a probe into the activities of Mick Mulvaney while he was acting head of the Consumer Financial Protection Bureau. Mulvaney is now the acting White House chief of staff.

"But it's not just Mick Mulvaney who I will be paying attention to," Waters said. "I will be keeping a watchful eye on all of the financial regulators to make sure that they are carrying out their statutory duties, including holding bad actors accountable, and promoting financial stability."

In addition to the threat against big banks, Waters said credit reporting agencies also would be scrutinized in the wake of the Equifax hacking scandal. The agency reported in 2017 that hackers had compromised personal information on more than 147 million Americans.
