Holly Petraeus did not attend her husband's Capitol Hill testimony on Friday regarding the Sept. 11 attacks on the U.S. Consulate in Benghazi, Libya.  

David Petraeus was sneaked into the Capitol away from photographers and television cameras for his first, closed-door congressional testimony since resigning as CIA director over an extramarital affair. He was guided into his House Intelligence Committee hearing "in a manner more suited to covert operatives:" through a network of underground hallways leading to a secure room, according to the Boston Herald. Capitol Hill police also blocked off doorways and back staircases.

CIA directors typically walk through the building's front door when coming to appear before Congress, however, David's secretive arrived may hint to the fact that the scandal involving his extramarital affair has caused a storm in Washington, the report added. 

The decision not to immediately inform Congress and the White House about the FBI investigation regarding David and his lover, and biographer, Paula Broadwell, raised questions and had certain members of Congress concerned.

Some Congress members announced on Nov. 11 that they want more details about the FBI investigation, questioning Petraeus' first involvement in the FBI investigation, whether national security was compromised and why they were not told sooner about the case, according to ClarionLedger.com.

Petraeus' appearance at Capitol Hill Friday comes exactly one week after he resigned as CIA director due to his affair with Broadwell. He told friends the affair began in August of 2011 after he left the army, according to ABC News.

The hearings focused on the Sept. 11 Benghazi attack on the U.S. Consulate. As for Petraeus testifying after his resignation and during an FBI investigation into his sex scandal, Rep. Adam Schiff (D-Calif) said, "He's a tough individual and I am sure he will handle it to the best of his ability."
