The top remaining enforcement official at the U.S. Consumer Financial Protection Bureau has tendered her resignation, saying the White House’s overhaul of the agency had made her position untenable, according to an email seen by Reuters.

Acting Enforcement Director Cara Petersen, who has served at the agency since its creation nearly 15 years ago, said that current leadership under President Donald Trump “has no intention to enforce the law in any meaningful way.”

“I have served under every director and acting director in the bureau’s history and never before have I seen the ability to perform our core mission so under attack,” Petersen wrote in an email.
