After receiving a vote of “no confidence” from the House Oversight and Government Reforms Committee, embattled DEA chief Michele Leonhart is expected to resign, an Obama administration official said Tuesday.

Leonhart, who has led the agency since 2007 and is the second woman to hold the job, has faced mounting pressure to resign after a scathing government watchdog report detailing allegations that agents attended sex parties with prostitutes.

Lawmakers have been eager to remove Leonhart from her position after her disastrous appearance before the House Oversight Committee last week. The committee said they had lost confidence in her and said she “lacks the authority and will to make the tough decisions required to hold those accountable who compromise national security and bring disgrace to their positions.”

Leonhart has previously been the target of online petitions calling for her ouster after she distanced herself from the administration’s stance on legalized marijuana, seen as a hands-off approach that lets states legalize marijuana so long as it is state regulated. Marijuana remains illegal under federal law and is classified by the DEA as a Schedule 1 drug, along with drugs such as heroin and peyote.[/su_quote]

“Leonhart’s DEA reflects an outdated, disastrous approach that President Obama claims he wants to leave behind,” said Bill Piper, director of national affairs for the Drug Policy Alliance. “If she leaves he has an opportunity to appoint someone who will overhaul the DEA and support drug policy reform.”

“The DEA is a large, expensive, scandal-prone bureaucracy that has failed to reduce drug-related problems,” said Piper. “Drug use should be treated as a health issue instead of a criminal justice issue; with states legalizing marijuana and adopting other drug policy reforms it is time to ask if the agency is even needed anymore.”
