Harvard Law Professor Alan Dershowitz said Thursday on "Tucker Carlson Tonight" that the Senate Judiciary Committee Republicans' chosen questioner did not act effectively during the Kavanaugh hearing.

Dershowitz said that Maricopa County, Ariz. prosecutor Rachel Mitchell was "totally and completely incompetent in terms of asking cross-examination questions, because she has little experience [doing so]."

Dershowitz recalled how Wednesday he predicted Mitchell would be a bad choice to lead Republicans' questioning of Judge Brett Kavanaugh and accuser Christine Blasey Ford.

"I turned out to be 100 percent right," he said.

Dershowitz said Mitchell may be an experienced prosecutor, but it is defense attorneys who are well-versed in cross-examining a witness.

"She accomplished nothing," Dershowitz said of much of Mitchell's line of questioning.

He said that Ford came off "extremely credible," and that Kavanaugh "made this remarkable comeback and testified in a completely compelling manner."
