Alan Dershowtiz appeared on "Fox & Friends" on Thursday to react to a report that the Justice Department inspector general has determined that former FBI Director James Comey defied authority at times and was "insubordinate."

Inspector General Michael Horowitz has been exploring the DOJ's and FBI's actions during the 2016 presidential campaign, including whether Comey exceeded his authority in July 2016 when he publicly discussed the Hillary Clinton email investigation and recommended no charges.

Dershowitz said somebody familiar with Horowitz's draft report leaked this information about Comey because they were "afraid it was going to get changed."

"They want people ... to see the original," Dershowitz said. "And I hope Horowitz holds on to the original draft, so he can be questioned about it."

He explained that Congress has the power to request Horowitz produce the original report, see what was changed and call in the people who made the changes to find out why.

"We're entitled to see every single draft," Dershowitz said.

He said the report also reinforces that there was no need to appoint Special Counsel Robert Mueller.

"We have the inspector general. He is independent, he does a great job. All of this could have been done through the Justice Department [and] regular lawyers," Dershowitz said. "You don't need to bring in a multi-million dollar group of people with a target on the back of specific individuals."

"That's not the way justice should operate."
