   House committee Chairman King asks for minute-by-minute timeline 
   
   The actions of a few should not denigrate the many professionals, Axelrod says

   A Senate committee will expand its probe into the U.S. Secret Service this week following a scandal involving prostitutes in Colombia in advance of a recent trip by the president. 
   
   The Homeland Security Committee will send the Secret Service "some questions this week, as the beginning of our broader investigation, asking whether... this was an exception, or is there anything in the records that show this is a pattern of misconduct that has gone on elsewhere by Secret Service agents on assignment, but off-duty?" Sen. Joe Lieberman, the committee chairman, told "Fox News Sunday." 
   
   "Why wasn't it noticed if that was the case? What's the Secret Service going to do to make sure it never happens again?" 
   
   Some Secret Service members and agents allegedly brought back several prostitutes to a hotel in Cartagena, according to sources familiar with the U.S. government's investigation. 
   
   The Secret Service says 12 members of the agency have been implicated in the incident.

   Across the Sunday political talk shows, officials expressed confidence in Secret Service Director Mark Sullivan, saying they believe he has handled the scandal well and will get answers. 
   
   "History is full of cases where enemies have compromised" people with security or intelligence information through sex, said Lieberman, I-Connecticut. He added that based on what he has been told so far, "there is no evidence that information was compromised" in this case. 
   
   Down the road, the committee will hold a public hearing on the matter -- perhaps more than one, Lieberman said. 
   
   "Anyone who's found to be guilty" will lose his job, Rep. Peter King, Chairman of the House Homeland Security Committee, told NBC's "Meet the Press." 
   
   King told CNN last week that four investigators were assigned to his committee's probe. 
   
   One person who was "partially exonerated" will instead likely face administrative action, King said. 
   
   In a letter sent to Sullivan on Friday, King listed a series of questions, including how many employees were aware of the alleged incident and how many total employees were in Cartagena in support of President Obama's trip to the Summit of the Americas when the incident occurred earlier this month. 
   
   "Please provide a comprehensive, minute-by-minute timeline of all known actions, locations, and possible violations of U.S. or Colombia law," codes of conduct, and directives, King wrote in the letter. 
   
   But King and other officials are quick to emphasize that those allegedly involved in cavorting with prostitutes at a hotel in Cartagena are the exceptions. 
   
   "In any organization things can go wrong," President Obama's chief campaign strategist David Axelrod told CNN's "State of the Union" Sunday. "I must say that in my experience the Secret Service has been completely professional, so impressive. I always felt like they were ... willing to do anything to protect the president and the people around the president. And so this was really disappointing. 
   
   "Obviously we have to get to the bottom of it, but those problems should not denigrate the efforts of so many who do such a good job." 
   
   Sen. Susan Collins, ranking member on the Homeland Security Committee, and Rep. Carolyn Maloney of the House Oversight Committee suggested having more female agents could help avoid such scandals. 
   
   "I can't help but wonder if there'd been more women as part of that detail if this ever would have happened," Collins told ABC's "This Week." 
   
   Maloney agreed, and added that she was told 11% of agents in the Secret Service are women. The agency did not immediately confirm the figure to CNN Sunday. 
   
   "We probably need to diversify the Secret Service and have more minorities and more women," she said. 
   
   Six Secret Service members have left their jobs in the wake of the incident in Cartagena, Colombia, which came while they were on a security detail in advance of President Obama's trip for the Summit of the Americas. 
   
   One employee "has been cleared of serious misconduct, but will face administrative action," the Secret Service said. 
   
   Five employees are on administrative leave and have had their security clearances temporarily revoked. 
   
   In addition, the U.S. military is investigating 11 of its own troops for possible heavy drinking and consorting with prostitutes. 
   
   White House staff have not been implicated in the controversy. 
   
   After the scandal broke, President Obama called for a "thorough" and "rigorous" invsetigation. "If it turns out that some of the allegations that have been made in the press are confirmed, then of course I'll be angry," he said. ||||| The chairman of a House committee investigating an alleged Secret Service prostitution scandal predicted more firings as key lawmakers and a top adviser to President Barack Obama expressed confidence Sunday that the agency will effectively deal with the incident.

   "Every possible lead is being examined," said Rep. Peter King, who heads the House Homeland Security Committee. King, R-N.Y., said he expected that in the "near future, several other" members of the Secret Service will leave. 
   
   "What they were thinking is beyond me," King told NBC's "Meet the Press." 
   
   So far, the scandal includes 12 Secret Service employees and 11 military members. 
   
   Six of the Secret Service members have lost their jobs. One has been cleared and five remain on administrative leave. The main incident occurred shortly before Obama arrived for a meeting of regional presidents last weekend. 
   
   A Secret Service official confirmed Sunday that one of the 12 implicated in the scandal was staying at a different hotel than the others. 
   
   He was staying at the Hilton, where Obama eventually would stay, said the official who spoke on the condition of anonymity because the official was not authorized to discuss the matter publicly. The agent is being investigated for improprieties in a separate incident that may have happened on April 9, days before the president arrived and while the hotel was still open to the general public. 
   
   Sen. Joe Lieberman, chairman of the Senate Homeland Security and Government Affairs Committee, also mentioned the 12th agent under investigation in an appearance on CBS's "Face the Nation." 
   
   "Now we don't know at this point what that 12th agent is being charged with and why he's been put on administrative leave. But now you're into the hotel where the president of the United States was going to stay. And it just gets more troubling," Lieberman said. 
   
   Lieberman told Fox News Sunday there is "no evidence that information was compromised" in the incidents. Those involved "were not acting like Secret Service agents. They were acting like a bunch of college students away on a spring student weekend," Lieberman said. 
   
   King, Lieberman and other leaders of congressional committees examining the scandal made the rounds on Sunday news shows. Generally, they said the scandal was being closely scrutinized on Capitol Hill and voiced support for Secret Service Director Mark Sullivan's handling of the matter. 
   
   Obama campaign adviser David Axelrod said the allegations are disturbing, but that the misdeeds of a few individuals should not tarnish the overall work and reputation of the service. 
   
   Axelrod told CNN's "State of the Union" that he always felt the agents were willing to go to great lengths to protect the president and the people around him. He called the conduct in Colombia "really disappointing." 
   
   "I think we will get to the bottom of it," said Axelrod, who worked at the White House before leaving last year to work full time in Obama's re-election campaign office in Chicago. 
   
   He later told NBC that "on the whole, the Secret Service does heroic work. This is quite disturbing. We have to get to the bottom of this, and I'm sure we will." 
   
   Sen. Tom Coburn, R-Okla., a frequent critic of the president, declined to fault the White House's response. "You know, I'm not critical of what the administration has done thus far," he told CBS. "I think what we're seeing is an aberration." 
   
   Sen. Susan Collins of Maine, the senior Republican on the Homeland Security Committee, and Rep. Carolyn Maloney, D-N.Y., both said that more female Secret Service agents might help guard against such incidents from happening again. 
   
   "I can't help but wonder if there had been more women as part of that detail, if this ever would have happened," Collins said on ABC's "This Week." 
   
   Maloney told the same program that only 11 percent of the Secret Service's agents are women. 
   
   "I can't help but keeping asking this question: Where are the women? We probably need to diversify the service and have more minorities and more women," Maloney said. 
   
   Rep. Darrell Issa, R-Calif., chairman of the House Oversight and Government Reform Committee, told NBC that the episode was "something the Secret Service can fix. We have confidence that it will be fixed." 
   
   "The most important thing is that this never happens again," Issa said. 
   
   Ralph Basham, a former Secret Service Director, told CBS the behavior of those implicated in the scandal "could have compromised the trip and the safety of the president."
target: – Heads probably haven't finished rolling at the Secret Service over its prostitution scandal, Rep. Peter King said today on Meet the Press, saying he expected "several" members to depart in the "near future." The House Homeland Security chair promised a thorough investigation, and has already sent a letter to the agency demanding answers to 50 questions, like whether agents used their expense accounts to pay their paramours, Fox News reports. He's not alone; the Senate will be expanding its investigation too, Joe Lieberman said today, according to CNN. Secret Service officials also confirmed today that one of the 12 agents implicated in the scandal so far was staying at a different hotel than the other 11—the same hotel that President Obama would eventually stay in, the AP reports. "It just gets more troubling," Lieberman said, though he cautioned that, "We don't know at this point what that 12th agent is being charged with."
