Rudy Giuliani, the personal lawyer for President Trump, said that former FBI Director James Comey could be prosecuted for his handling of the Hillary Clinton email probe based on an upcoming report from the Department of Justice’s internal watchdog.

“I think the report of Horowitz, the IG, and the Justice Department will confirm that Comey acted improperly with regard to the Hillary Clinton investigation,” Giuliani told John Catsimatidis on his AM 970 radio show on Sunday, referring to Inspector General Michael Horowitz.

“The first thing we are going to get is a report from Inspector General Horowitz on Comey’s handling of Hillary, which I think is going to be very very critical of Comey, as it should be,” Giuliani continued.

“Comey, really, has a chance of being prosecuted as a result of, but we’ll see.”

Horowitz on Thursday is expected to release the report on Comey’s role in the FBI’s investigation into Clinton’s use of a private email server when she was secretary of state.

Parts of the report that have surfaced in the media claim that Comey was “insubordinate” and faulted him for ignoring the DOJ’s objections when he informed Congress in a letter weeks before the 2016 election that he was reopening the investigation into Clinton’s emails.

Clinton’s camp has claimed that Comey’s action delivered a fatal blow to her presidential campaign.

The DOJ inspector general launched the examination into the probe surrounding Clinton’s emails days before Trump was inaugurated in January 2017.

Trump fired Comey in May 2017, paving the way for the appointment of special counsel Robert Mueller, who’s investigating Russian involvement in the election.
