(CBS/AP) WASHINGTON - The U.S. military says 11 service members are being investigated for alleged misconduct in Colombia. That's up from the 10 personnel the military last believed to be involved.
The military says six are from the Army, two each are from the Marines and Navy and one is from the Air Force. The Marine and Navy personnel are from San Diego and the Air Force member is from Charleston, S.C. The Army personnel are from the 7th Special Forces Group.
The military says the service members have returned to their commands. It says they have not been charged and are not under detention.
The service members were staying in the same Colombian hotel as 11 Secret Service employees who are under investigation for alleged misconduct involving prostitutes.
At least three more Secret Service officers were expected to lose their jobs Friday, a federal official told The Associated Press.
The lawyer for two Secret Service supervisors said Friday that President Barack Obama's safety was never at risk and criticized leaks of internal government investigations in the case, signaling their strategy for an upcoming legal defense.
Meanwhile, on Capitol Hill, the Secret Service briefed congressional officials behind closed doors about details in the scandal.
The disciplinary announcement expected later Friday would bring to six the number of Secret Service employees who no longer work for the agency in the wake of the scandal. The federal official spoke on condition of anonymity because this person was not authorized to disclose the news ahead of the announcement.
Eleven Secret Service employees were put on administrative leave last week following an incident in Colombia that involved at least some agency personnel bringing prostitutes to their hotel room. The scandal, which involves as many as 20 Colombian women, broke last week after a fight over payment between a prostitute and a Secret Service agent spilled into the hotel hallway. A 24-year-old Colombian prostitute told The New York Times that the agent agreed to pay her $800 for a night of sex but the next morning offered her only $30. She eventually left the hotel, she told the newspaper, after she was paid $225.
The scandal involved 11 officers and supervisors and at least 11 military members who were working on security before President Barack Obama arrived in Cartagena, Colombia, for the Summit of the Americas last week. The Pentagon acknowledged Friday that an 11th military person, a member of the Army, was implicated in the scandal.
Sources tell CBS News Secret Service officials believe their personnel picked up women at four different locations in Cartagena.
The lawyer for ousted Secret Service supervisors David Chaney and Greg Stokes, Lawrence Berger of New York, said Friday that Obama's safety was never at risk and said leaks surrounding the ongoing investigations "distort the process."
Regardless of what happened inside hotel rooms, Berger said, it never jeopardized the president's security. Berger said he could not comment on the woman's claims about being paid for sex, but added, "I don't think anything she has said is material to any of the issues I am pressing with my clients."
"Nothing that has been reported in the press in any way negatively or adversely impacted the mission of that agency or the safety of the president of the United States," Berger said.
Chaney and Stokes were forced out of the agency Wednesday. A third agent, who has not been identified and was not a supervisor, resigned.
On Chaney's Facebook account, which was made inaccessible on Friday, Chaney joked that he was checking out former Republican vice presidential candidate Sarah Palin while he was protecting her in 2008. The AP published a photograph it took of Chaney working in Palin's protective detail in October 2008 during a campaign rally in Carson, Calif.
"I was really checking her out, if you know what i (sic) mean?" Chaney wrote after a friend commented on the picture posted in January 2009 on Chaney's Facebook account.
Speaking on Fox News late Thursday, Palin said the joke was on Chaney.
"Well check this out, buddy you're fired!" Palin said.
All the 11 Secret Service employees have had their top-secret security clearances lifted.
The Secret Service investigation has included interviews of agents and hotel staff. Rep. Peter King, chairman of the House Homeland Security Committee, said this week that investigators in Colombia have not been able to interview the women.
The tawdry affair has also prompted a military investigation of 11 service members, including six members of the Army, two Navy Explosive Ordinance Disposal technicians, two Marine dog handlers and an Air Force airman.
An Air Force colonel and a military lawyer were also dispatched to Colombia this week. Under the Uniform Code of Military Justice, patronizing prostitutes is a crime for military personnel. It is referred to as "compelling, inducing, enticing or procuring a person to have sex in exchange for money; or receiving money for arranged sex." The UCMJ applies regardless of whether the service member is in the U.S. or abroad.
Officials from U.S. Southern Command, which organized the military role for the security operation, have not provided details of its probe beyond saying that at least some of the military members violated curfew and may have been involved in "inappropriate conduct."
White House press secretary Jay Carney said it was "preposterous to politicize" the issue, responding to criticism from Alabama Sen. Jeff Sessions and Palin, who have said the allegations reflect poor management of the government under Obama.
Palin described the affair Thursday as a "symptom of government run amok."
"It's like, who's minding the store around here?" Palin told Fox.
Carney said Obama had not had any conversations with Secret Service Director Mark Sullivan but wouldn't rule out that they may speak soon.
