Rep. Darrell Issa (R-CA) was escorted out of Tuesday’s Benghazi deposition by panel chairman Rep. Trey Gowdy (R-SC) about a minute after he snuck into the private session, The Hill reported.

The former House Oversight Chairman reportedly attempted to observe Sidney Blumenthal’s deposition before the House Select Committee. Blumenthal was an adviser to 2016 Democratic presidential candidate Hillary Clinton.

Issa and Gowdy spoke outside the deposition before Issa sulked off, according to The Hill.

“Sorry about that,” Gowdy reportedly said as he reentered the closed-door session.

According to The Hill, Issa had gone to the briefing room where Blumenthal was to be interviewed but the room was empty as a lunch recess had been called.

Blumenthal is being questioned about 60 emails he exchanged with Clinton during Clinton’s time as Secretary of State, Politico reported. The newly-surfaced emails may suggest that Clinton withheld correspondence from the panel as it attempts to determine what happened in Benghazi, Libya.

On Sept. 11, 2012, Islamic terrorists attacked the U.S. Consulate in Libya, killing a U.S. ambassador, an information officer and two CIA operatives.
