In an exclusive interview with Fox News host Bret Baier that aired Tuesday, Attorney General Willaim Barr revealed that the U.S. Attorney John Durham is investigating “some” known names in his probe, saying that he’s “very troubled” from what he knows so far.

“I think before the election, I think we’re concerned about the motive force behind the very aggressive investigation that was launched into the Trump campaign without, you know, with a very thin, slender reed as a basis for it,” Barr told Baier.

“It seemed that the bureau was sort of spring-loaded at the end of July to drive in there and investigate a campaign.”

A number of those familiar names are expected to be a number of former Obama administration officials who ‘unmasked’ members of Trump’s team.

“We can’t discuss future charges. But I have to say that I do find a little irritating,” Barr added.

“You know, the propensity in the American public on all sides of the political spectrum when they see something they think could be a criminal violation, I say, why hasn’t this person been indicted again? And, you know, there’s the old saying that that the wheels of justice grind slow and they do run slow because we have due process and we follow the process. But people should not draw from the fact that no action has been taken that taken yet, that that means that people or people are going to get away with wrongdoing.”
