New York (CNN) Consumer advocates raised big concerns this week about the two top officials the Trump administration has appointed to protect Americans from fraud, claiming one has no related experience and that the other won't be able to go after companies like Equifax, Facebook, Amazon and Verizon because of his work in the private sector.

On Thursday, in a party-line vote, the Senate confirmed Kathy Kraninger to head the Consumer Financial Protection Bureau. Democrats fear she will undercut the agency, which was put in place after the financial crisis to make sure banks and lenders don't cheat consumers.

"Kathy Kraninger has no consumer protection or financial regulation experience. We expect her to simply follow Mick Mulvaney's playbook," said Ethan Lutz, a consumer fellow at the left-leaning watchdog group US PIRG.

Kraninger worked under Mulvaney at the Office of Management and Budget.
