"As we noted publicly last year in our report, we were very concerned about that," Horowitz told the Senate Judiciary Committee.

"We are investigating those contacts. We've issued a couple of public summaries so far about people we've found violated FBI policy. We have other investigations ongoing," Horowitz continued.

He added that, while it has been hard to prove the substance of conversations between FBI and reporters or outside individuals, “we can prove the contacts."

"Under FBI policy, you need authorization if you're going to disclose information and have certain contacts," he said.

"Mr. Giuliani now professes to be President Trump's lawyer and occasionally the president acknowledges that, sometimes he doesn't," Durbin said.

Durbin also asked Horowitz if there were "any concerns" that Giuliani is continuing to "improperly obtain" information from law enforcement sources.

Horowitz said that he was not investigating matters related to Ukraine, to which he believed Durbin was referring.

Horowitz is testifying on the IG report released this week on alleged surveillance by the FBI during the 2016 presidential campaign. The Hill is providing running updates on the hearing.
