A former FBI official said Sunday that Bill and Hillary Clinton are part of a “crime family” and added that top officials impeded the investigation into Clinton’s email server while she was secretary of state.

Former assistant FBI director James Kallstrom praised Donald Trump before he offered a take down of the Clintons in a radio interview with John Catsimatidis, The Hill reported.

“The Clintons, that’s a crime family, basically,” Kallstrom said. “It’s like organized crime. I mean the Clinton Foundation is a cesspool.”

Kallstrom, best known for spearheading the investigation into the explosion of TWA flight 800 in the late ’90s, called Clinton a “pathological liar” and blamed Attorney General Loretta Lynch for botching the Clinton email server investigation.

“The problem here is this investigation was never a real investigation,” he said. “That’s the problem. They never had a grand jury empanelled, and the reason they never had a grand jury empanelled, I’m sure, is Loretta Lynch would not go along with that.”

“God forbid we put someone like that in the White House,” he added of Clinton.

Kallstrom blamed the FBI leadership under FBI Director James Comey as the reason the investigation was held back, but not the rest of the bureau.

“The agents are furious with what’s going on, I know that for a fact,” he said.
