U.S. Rep. Peter King, who was briefed Saturday on the investigation, tells The Associated Press that “close to” all 11 of the agents involved had women in the rooms at their hotel, which was separate from the one where Obama is now staying.

The New York Republican says the women were “presumed to be prostitutes,” but investigators are interviewing the agents. King heads the House Homeland Security Committee…

A senior law enforcement official told Fox News the dispute started when employees at the hotel witnessed apparent inappropriate behavior by at least one of the Secret Service agents.

According to the official, a hotel employee confronted at least one agent to demand he pay extra money for having an overnight “guest” in his room — allegedly a prostitute. The agent balked, which touched off the confrontation that forced diplomatic intervention.
