Former House select committee investigator Maj. Bradley Podliska says that he was fired, in part, because he attempted to launch an probe into the 2012 Benghazi attack. He claims that he angered his superior officers by not focusing on Hillary Clinton and her role in the attack instead, according to The New York Times.

Podliska serves in the Air Force Reserve. The House Select Committee, which has led the Congressional Benghazi probe, says that he was "terminated for cause."

"This Republican whistleblower's account from inside the Benghazi committee may provide the most definitive proof to date that this taxpayer-funded investigation has been a partisan sham from the start," Clinton's press secretary Brian Fallon said, CNN reported.

"These are extremely serious whistleblower charges by one of Chairman Gowdy's own handpicked investigators," said Rep. Elijah Cummings (D-Mary.), who is on the House Benghazi committee.

Podliska is not the first to suggest that the committee is less about investigating the attack in Benghazi and much more about politics in Washington, D.C. The select committee has been the subject of criticism since Rep. Kevin McCarthy (R-Calif.) suggested that the Benghazi investigation was used to undermine Clinton in the polls.

Clinton was serving as Secretary of State during the attack, which claimed the lives of four Americans, according to The Guardian.
