WASHINGTON (Reuters) - The fight for control of the U.S. consumer watchdog agency intensified on Monday as Mick Mulvaney, President Donald Trump’s pick to run the Consumer Financial Protection Bureau (CFPB), imposed a hiring freeze and halted any new regulations.

In a partisan showdown over the CFPB, which was created to crack down on predatory financial practices, Mulvaney is being sued by Leandra English, an Obama-era appointee to the agency who argues that she is the consumer bureau’s rightful leader.

The conflict began on Friday when Richard Cordray, a Democrat appointed CFPB director by then-President Barack Obama, formally resigned and named English, his chief of staff, as acting director. Hours later, Trump named Mulvaney, the current director of the White House budget office, as temporary head of the CFPB.

Mulvaney, who sought to dismantle the CFPB when he was a Republican congressman, acknowledged at a news briefing on Monday afternoon that the Trump administration had a “dramatically different” interpretation of the 2010 Dodd-Frank law that created the CFPB.

He said there would be a 30-day freeze on hiring at the agency and no payments from the CFPB’s civil penalties fund for that amount of time as well, except as required legally. All new regulations would also be frozen, he said.

“The president has made it very clear he wants me here. ... I want to be here. I don’t want anything coming out of here that I don’t know about,” Mulvaney said.

DUELING ‘ACTING DIRECTORS’

Earlier on Monday, English welcomed staff back from the Thanksgiving holiday in a morning email and signed off as “acting director.”

Around the same time, Mulvaney arrived at Cordray’s former office, bringing doughnuts for the staff.

“Please disregard any instructions you receive from Ms. English in her presumed capacity as Acting Director,” he wrote in an all-staff email seen by Reuters that he also signed “acting director.”

Mulvaney advised staff members to inform the agency’s general counsel if they heard additional communications from English.

As Mulvaney was getting settled in, a source told Reuters, CFPB general counsel Mary McLeod sent a memo agreeing with the U.S. Justice Department that Trump had the power to appoint Mulvaney as temporary leader of the watchdog.

English went to the CFPB in the morning, according to her lawyer. She then met on Capitol Hill with Senate Democratic leader Chuck Schumer and Democratic Senator Elizabeth Warren, who conceived the CFPB.

English told reporters that “Mulvaney has no authority” at the agency.

Schumer said on the Senate floor that the Dodd-Frank law, which he helped to write, set up a “clear” succession process for the CFPB that made English the acting director.

Schumer said Mulvaney was chosen by the Trump administration simply to “rock the agency from the inside.”

Trump campaigned for president saying Wall Street “gets away with murder,” but he also promised to defang or abolish the CFPB.
