John Brennan, President Obama’s nominee to head to the CIA, is scheduled to appear before a closed-door hearing held by the Senate Intelligence Committee tomorrow. Interested senators should take the opportunity to ask Brennan about an Egyptian who is connected to both al Qaeda and the September 11, 2012 terrorist attack in Benghazi, Libya. Intriguing revelations by the Egyptian press last week raise all new questions about the attack on the U.S. consulate.

The Egyptian in question is Muhammad Jamal (a.k.a. Abu Ahmed, sometimes referred to as Mohammad Jamal Abdo Ahmed, or Muhammad Jamal al Kashef), who served under Ayman al Zawahiri in the Egyptian Islamic Jihad during the 1990s. Jamal was freed from prison following the revolution that swept Hosni Mubarak from power. He quickly got back to work, establishing training camps in the Sinai and Libya.
