WASHINGTON (November 15, 2012)--Former CIA Director David Petraeus said Thursday in an interview with CNN he never gave any classified information to Paula Broadwell.

It was his first interview since he was forced to resign because of the affair.

According to a law enforcement official, the FBI has found a substantial number of classified documents on Broadwell's computer and in her home.

The official said Broadwell told agents that she took classified documents out of secure government buildings.

The Army has now suspended her security clearance, which she had as a former Army intelligence officer.

President Barack Obama said Wednesday that he's seen no evidence that national security was damaged, but members of Congress have been grilling CIA and FBI officials privately to see if that's the case.

Petraeus also told CNN that his resignation had nothing to do with his upcoming testimony to Congress about the attack on the U.S. consulate in Benghazi, Libya in September that left the U.S. ambassador and three other Americans dead.

Petraeus said he wanted to testify about the Libya matter and he’ll testify Friday before the House Intelligence committee in a hearing that will be closed to the public.
