Drug Enforcement Administration agents attended sex parties with prostitutes while stationed overseas as far back as 2001, according to a report released Tuesday. At a hearing Tuesday, Leonhart, was sharply questioned and asked why agents were not fired, nor their names released.

WASHINGTON — The chairman of the House Oversight Committee says the head of the Drug Enforcement Administration should step down amid allegations that DEA agents attended sex parties with prostitutes while stationed overseas.

Republican Rep. Jason Chaffetz of Utah said Tuesday that DEA chief Michele Leonhart has allowed problems at the agency to fester for more than a decade. He told The Associated Press, "It's time for her to go."

Chaffetz made the comment after a 3 ½-hour hearing Tuesday that focused on the sex party allegations, which date back to 2001. Leonhart has led the DEA since 2007 and was sole deputy for three years before that.

An internal report released Tuesday said government money was used to pay prostitutes at a farewell party for a high-ranking DEA official in Colombia.
