US Drug Enforcement Administration agents had alleged “sex parties” with prostitutes over several years, a report stemming from a review of allegations of misconduct by several DEA agents in Colombia said.

The US Secret Service director has told lawmakers she takes full responsibility for the serious breach of White House security when an Army veteran with a knife climbed the fence and made his way into the executive mansion before he was tackled.

US president Barack Obama broke his silence over claims that Secret Service agents hired prostitutes and said “of course I’ll be angry” if the accusations were true.
