“I think the report is going to be devastating to the president and I know that the president's team is already working on a response to the report,” Dershowitz said on "This Week" Sunday.

Dershowitz added that he believes the report, although it will have a strong political impact, is unlikely to result in criminal charges.

“When I say devastating, I mean it's going to paint a picture that's going to be politically very devastating. I still don't think it's going to make a criminal case,” Dershowitz said.
