Commenting on President Donald Trump's tweets about alleged Russia-Trump campaign collusion, famed attorney and constitutional scholar Alan Dershowitz said "the president is 100% right," a special counsel never should have been appointed, and added that he has "seen no evidence to suggest that crimes have been committed by the president."

“First of all, the president is 100% right," said the liberal Dershowitz on the March 20 edition of Fox & Friends. "There never should have been the appointment of a special counsel here. There was no probable cause at that point to believe that crimes had been committed."

"I’ve seen no evidence to suggest that crimes have been committed by the president," he said.

Dershowitz, who supported Hillary Clinton in the 2016 presidential race, continued, "As I said from day one, there should have been a simple investigative commission, non-partisan, appointed by Congress, with subpoena power to look into the role of Russia in trying to influence American elections and to try to do something about preventing it in the future – instead of starting out with finger-pointing and trying to criminalize political differences behind the closed doors of a grand jury."

"That’s gotten us nowhere," he said. "The president is absolutely right: this investigation never should have begun."

"And the question is now, how does he deal with it?" said the long-time criminal defense attorney.

"I think what he’s doing is playing good cop, bad cop," said Dershowitz. "He has some of his lawyers cooperating with Mueller, and some of his lawyers attacking Mueller because he wants to be ready to attack in the event there are any recommendations that are negative to the president."
