A senior Republican on the Senate's homeland security committee says at least 20 foreign women were involved in an incident in Colombia involving Secret Service agents, military personnel and prostitutes.

Maine Republican Sen. Susan Collins said Tuesday that Secret Service Director Mark Sullivan told her that 20 or 21 foreign women were brought to the hotel where 11 Secret Service agents and Marines were before President Barack Obama's visit to Colombia. Those Secret service agents have been recalled and interviewed, Collins said Sullivan reported. But Collins said she remains concerned about whether any of the women posed a security threat to the United States or Obama.


Pentagon officials said Monday that as many as 10 military members may have been involved. Congressional committees are looking into the matter.
