Legislator: Secret Service to change its rules Agents will be barred from places of "bad acts" or bringing foreigners to their rooms The moves are in response to scandal over alleged hiring of prostitutes in Colombia Rep. Sheila Jackson Lee outlines the changes after talking to the Secret Service director Jackson Lee appeared on CNN's "Erin Burnett OutFront" on Thursday night (CNN) -- Secret Service agents on the job will no longer be allowed to go to places of "bad acts" or bring foreigners to their hotel rooms. The new rules come in response to the scandal over alleged hiring of prostitutes in Colombia, a legislator said after speaking to agency Director Mark Sullivan. "If this is the culture, then they want to immediately put it to rest," Rep. Sheila Jackson Lee, D-Texas, said Thursday night on CNN's "Erin Burnett OutFront," after meeting with Sullivan about the controversy that has embarrassed the 147-year-old agency and raised questions about possible security breaches. In addition to setting up working groups focused on its culture and outreach efforts, the Secret Service will institute other measures, according to Jackson Lee. "More importantly, we're going to be saying that no foreign national will be allowed in your room, it will be absolutely illegal in terms of your job for you to in essence attend or be associated with any place of bad acts, and then finally a professional development officer or personnel officer is going to go along on every trip that the agents take out of the country," she said. The Secret Service continued to be rocked by allegations of transgressions by its agents, including reported heavy drinking and consorting with prostitutes earlier this month before President Barack Obama arrived in Cartagena, Colombia, for the Summit of the Americas. New claims include an account from El Salvador described by CNN affiliate Seattle TV station KIRO as very similar to the Colombia scandal, involving members of the Secret Service and other government agencies. A U.S. government official, speaking on condition of not being identified, acknowledged there had been missteps among Secret Service members. Such problems are to be expected over the agency's long history and don't necessarily reflect a systemic or cultural issue, the official said. "We have had employees that have engaged in misconduct," the official said. People make mistakes. Meanwhile, a congressional source said Thursday that reports of other incidents involving members of the agency, which is charged with protecting the president and other top officials as well as investigating criminal activity, have been brought to the attention of Congress. That includes the alleged incident in El Salvador, which the Secret Service has told Congress it is looking into as well, according to the congressional source. The KIRO report cited an unnamed U.S. government contractor who worked extensively with the Secret Service advance team in San Salvador before Obama's trip there in March 2011. The source said he was with about a dozen Secret Service agents and a few U.S. military specialists at a strip club in the city a few days before Obama arrived. The station reported that the strip club's owner corroborated the allegations. The owner confirmed that a large number of agents, and some military escorts, "descended on his club" that week and were there at least three nights in a row, KIRO reported. The owner said his club routinely takes care of high-ranking employees of the U.S. Embassy in San Salvador as well as visiting agents from the FBI and U.S. Drug Enforcement Administration, KIRO said. The government contractor source said he told the agents it was a "really bad idea" to take the strippers back to their hotel rooms, but several agents bragged that they "did this all the time" and "not to worry about it," KIRO reported. KIRO investigative reporter Chris Halsne told the CBS show "This Morning" on Thursday that he considers his source very credible, and he later told CNN that he had checked billing records, receipts, credentials and other information to confirm the contractor was with the Secret Service in Central America at the time of the incident. The source told him about the alleged scandal last year, while Halsne was in El Salvador on a different story. Halsne said he pressed for details at that time, but the man didn't want any information from him to be used then in a news story. After the allegations involving Secret Service agents in Colombia surfaced, Halsne again pressed his source, who this time agreed to the use of his account in the KIRO report. Responding to the KIRO report, Secret Service spokesman Edwin Donovan said: "The recent investigation in Cartagena has generated several news stories that contain allegations by mostly unnamed sources. Any information brought to our attention that can be assessed as credible will be followed up on in an appropriate manner. Defense Secretary Leon Panetta said Thursday that his department is not investigating any of its troops over the reported incident in El Salvador. But the State Department is questioning its embassy staff in El Salvador about the allegations, spokeswoman Victoria Nuland said Thursday. The Drug Enforcement Administration also is prepared to look into, "in an appropriate manner and immediately," allegations that it deems "credible" regarding its agents in El Salvador, agency spokesman Rusty Payne said. But he added that, while the DEA has seen news reports, "We are unaware of any allegations of misconduct." Sen. Chuck Grassley of Iowa -- the top Republican on the Senate Judiciary Committee, which received a briefing on the Colombia scandal this week by Homeland Security Secretary Janet Napolitano -- said the KIRO report "only reaffirms the need for independent investigations by the (Homeland Security Department's independent) inspector general." "There are rumors flying about various incidents over several years about the conduct of Secret Service personnel, as well as other law enforcement and military personnel in locations around the world," Grassley said. The only way to put to rest the rumors of a much wider problem is for the allegations to receive transparent and independent reviews. Another conservative Republican on the judiciary panel, Sen. John Cornyn of Texas, called for Congress itself to investigate "as part of our oversight responsibilities." But Sen. Chuck Schumer, a New York Democrat and Judiciary Committee member, disagreed and said Napolitano's investigation needs to come first. "After that, Congress should look into it and see what went wrong and what could be changed," Schumer said. The Washington Post reported Thursday that an unnamed source said such behavior is part of the culture at the Secret Service and not a one-time occurrence. The Secret Service said it has no comment on the Post story, but a Secret Service official, who was not authorized to comment on the continuing investigation said, "It's difficult for the Secret Service to defend against this," referring to the Post's article. "The reaction by our leadership speaks for itself," the official told CNN, referring to the Colombia incident. White House spokesman Jay Carney declined to comment on the new allegations Thursday, saying questions should be directed to the Secret Service. Nine Secret Service members have resigned or are being forced out as a result of the scandal over the alleged events in Colombia. The military has launched its own investigation into 12 members who were in Colombia in advance of Obama's visit.
