The House Select Committee on Benghazi has “bungled” its investigation into former Secretary of State Hillary Clinton and the deaths of four Americans in 2012, said Tom Fitton, the head of conservative watchdog group Judicial Watch.

“They have this almost petty approach to transparency that is at odds with the public interest,” Fitton told the Washington Post in an interview published Thursday. “It’s not supposed to be a grand-jury style investigation that the public can’t be privy to. There’s got to be at least some public forum for gathering testimony and evidence and that hasn’t happened here to any significant degree.”
