Attorney General William Barr wants to know what government officials were doing at the start of the Trump-Russia investigation.

"If we’re worried about foreign influence, for the very same reason, we should be worried about whether government officials abused their power and put their thumb on the scale,” Barr said in a Fox News interview set to air Friday. “And so I’m not saying that happened, but I am saying we have to look at that.”

Barr is investigating whether the Department of Justice and FBI acted appropriately at the beginning of the investigation led by special counsel Robert Mueller into Russian efforts to interfere in the 2016 presidential election.

While he has “been trying to get answers to questions,” he said, a lot of the answers have fallen short or "don’t hang together."

“In a sense, I have more questions today than when I first started,” Barr said.

President Trump himself viewed the Mueller investigation with suspicion from the beginning, repeatedly calling it a politically-motivated "witch hunt."

And Republicans have called for investigating the investigators for more than two years now, with those calls increasing following the conclusion of Mueller's investigation. The 448-page redacted Mueller report showed Russia had interfered in the 2016 election through cyber attacks and social media disinformation campaigns, but it did not establish that anyone on the Trump campaign engaged in a criminal conspiracy with the Russians.

Barr previously told the Senate Judiciary Committee that he is looking into the origins of the investigation into Trump, the existence of any criminal leaks from the FBI or DOJ to the media, the possibility that the salacious dossier compiled by former British spy Christopher Steele was influenced by Russian disinformation, whether the Foreign Intelligence Surveillance Act was abused, and more.

“I think people have to find out what the government was doing during that period," Barr said Thursday.
