The acting head of the Drug Enforcement Administration, Chuck Rosenberg, is stepping down.
Rosenberg was previously a U.S. Attorney in Texas and Virginia under former President George W. Bush. After that, he served as former FBI Director James Comey's chief of staff.
The New York Times reports officials say Rosenberg could be leaving, in part, because of President Donald Trump.
In July, Trump gave a speech to local, state and federal law enforcement. Rosenberg told DEA staffers in an email a day after that part of Trump's talk seemed to condone police misconduct.
"You just see them thrown in, rough — I said, please don't be too nice," Trump said. "Like, when you guys put somebody in the car and you're protecting their head, you know, the way you put their hand over? Like, don't hit their head, and they've just killed somebody — don't hit their head. I said, you can take the hand away, OK?"
Also in that July internal email, Rosenberg reinforced the agency's values, adding, "We must earn and keep the public trust and continue to hold ourselves to the very highest standards."
ABC News reports the Justice Department is looking for Rosenberg's replacement.
