The Republican-led House Select Committee on Benghazi hastily deleted the name of a high-level Libyan defector from one of its public releases on Monday, shortly after Yahoo News reported the panel had inadvertently revealed the defector’s name in an effort to embarrass Hillary Clinton.

The disclosure, followed by the quick wiping out of the name of ex-Libyan foreign minister Moussa Koussa (who had defected and become a source for the CIA on Libya), once again put the panel on the defensive on the eve of Thursday’s slated testimony from Clinton.

The incident was especially awkward for GOP chairman Rep. Trey Gowdy because just two weeks ago he had sought to make an issue over Clinton’s handling of an email that contained Koussa’s name.

At the time, Gowdy said, an email sent to Clinton on March 18, 2011, by her longtime friend and adviser Sidney Blumenthal contained the “name of a human source” for the CIA and was therefore “some of the most protected information in our intelligence community.”
