The head of the Drug Enforcement Administration will retire next month following a scandal over reports DEA agents in Colombia participated in sex parties with prostitutes hired by drug cartels. Michele Leonhart has also opposed Obama on marijuana policy, criticizing the Justice Department for deciding not to sue states that have legalized pot. The Drug Policy Alliance has launched a petition calling for Obama to appoint a replacement who will “help reduce mass incarceration that is a result of the failed war on drugs.”
