WASHINGTON >> With emails, tweets and doughnuts, dueling acting directors battled for control of the Consumer Financial Protection Bureau today.

Leandra English, who was elevated to interim director of the bureau last week by its outgoing director, sent staff an email offering Thanksgiving wishes. President Donald Trump’s choice for the role — White House budget director Mick Mulvaney — then emailed staff to tell them to “disregard” any instructions from English.

Laying down markers in what has quickly become a war of optics, both signed their missives “Acting Director.”

English has asked a judge to issue a temporary restraining order to block Mulvaney from taking over the bureau. She cited the Dodd-Frank Act, which created the Consumer Financial Protection Bureau. She said that as deputy director, she became the acting director under the law and argued that the federal law the White House contends supports Trump’s appointment of Mulvaney doesn’t apply when another statute designates a successor.

English was promoted to chief of staff to deputy director by Richard Cordray as he prepared to resign last Friday. Cordray was appointed to the position by President Barack Obama and has been long criticized by congressional Republicans as overzealous. He was one of the last Obama-era holdouts.

Mulvaney, a former Republican congressman from South Carolina, has called the agency a “joke” and an example of bureaucracy run amok. He is expected to be critical of the bureau’s previous work and will likely push to dismantle some of the agency’s previous actions.

Cordray said today that the issue should be settled by a court.

“The law says that I shall appoint the deputy director, and I did so,” he said. “My understanding of the law is that the deputy director becomes the acting director upon my departure. If there are disagreements about those issues, then they should be settled in the courts.”

Mulvaney arrived this morning at the agency with doughnuts, and his staff tweeted out photos of him meeting with agency division heads. Meanwhile, English sent a department-wide email saying she hoped everyone had a great Thanksgiving and signed it “Acting Director.” English also plans to have meetings on Capitol Hill, including with Sen. Elizabeth Warren, D-Mass.

Mulvaney quickly responded to English’s email, saying to “disregard” any directions from her.

At the center of the controversy are two laws: the Dodd-Frank Act, the law passed after the financial crisis that created the bureau, and the Federal Vacancies Reform Act, which gives the president authority to appoint temporary department heads while their permanent nominees are approved by the Senate.

While the Vacancies Act does allow a president to appoint acting directors at agencies like the CFPB, the Dodd-Frank Act has specific language that seems to indicate that only a deputy director can step into the acting director position. English was elevated to the deputy director position shortly before Cordray resigned.

English’s push to be recognized as the legitimate acting director took a blow after a memo was released today from Mary McLeod, the CFPB’s general counsel, saying she agreed with the White House that Mulvaney should be recognized as acting director.

The Office of Legal Counsel, which acts as a legal adviser to the president, also argued that Mulvaney, not English, was the legitimate director of the department.

White House press secretary Sarah Huckabee Sanders said “there should be no question” that Mulvaney is in charge of the agency, adding it was an unfortunate “stunt” for former director Richard Cordray to appoint an acting successor when he left office.

One straightforward solution to the issue of who is in charge at the CFPB is for Trump to nominate his own permanent director. But it may take several weeks for someone to be nominated and even months until the Senate were to confirm his or her appointment.

Until the issue of who is in charge is cleared up, any actions taken by the CFPB are likely to come under legal scrutiny from the banks, credit card and other financial companies that the agency oversees. No fines are likely to be imposed or new regulations written.
