FBI agents have been seen at the home of the woman whose affair with retired General David Petraeus led to his resignation as CIA director.
A spokeswoman for the FBI says that agents went to Paula Broadwell's home in Charlotte, North Carolina. FBI spokeswoman Shelley Lynch declined to say what the agents were doing there.
FBI agents appeared at Ms Broadwell's home carrying the kinds of cardboard boxes often used for evidence gathering during a search.
One person was taking photographs of the house and its garage as members of the news media watched.
General John Allen is being investigated for "inappropriate communication" with the woman at the centre of the CIA affair scandal.
The director of the CIA, General David Petraeus tendered his resignation as head of the leading U.S. spy agency on Friday.
