As the fallout from the Secret Service prostitution scandal continues, a new report surfaced Wednesday suggesting cocaine may have been present in one of the Colombia hotel rooms where agents and military personnel met prostitutes.

An employee at the five-star Hotel Caribe in Cartagena told the New York Post he went up to the hotel room with police and other staff after a dispute arose with one of the women.

“When I went upstairs I walked into a messy room. The room was littered with two whiskey bottles — and a line of white powder, I believed to be cocaine, was on top of a round glass table in the room,” he told the newspaper.

He painted a picture of morning-after mayhem in the lobby — just two days before President Obama landed in the country for an international summit.

“The prostitute was screaming in the lobby that he didn’t pay her,” the early-morning shift worker recalled. “She looked like she had a few drinks in her. She just wanted what was promised to her.

“She was very upset,” he said.

Secret Service Director Mark Sullivan said Tuesday 11 agents met with 11 foreign women at the hotel, and that military personnel were involved with more. Sen. Susan Collins, the ranking Republican on the Homeland Security Committee, said  “20 or 21 women foreign nationals” were involved in total.

An investigation is ongoing.

On Wednesday, Republican presidential candidate Mitt Romney said on Laura Ingraham’s radio program he would “clean house” at the agency to remove the agents involved in the scandal.

“The right thing to do is to remove people who have violated the public trust and have put their play time and their personal interests ahead of the interests of the nation,” Romney said
