Alan Dershowitz said Robert Mueller's investigation should come to a close because "a special counsel is the worst way of getting to the truth."

In recent weeks, Trump's attorneys and supporters have been calling for Mueller to wrap up his investigation into alleged collusion between the Trump campaign and Russia.

"This case is essentially over," Rudy Giuliani said on "The Ingraham Angle" last week. "They're just in denial."

On "Fox & Friends," Dershowitz, Harvard law professor emeritus, said it's important that we get to the bottom of how Russia interfered in the 2016 election, but that should be done by an independent, nonpartisan commission, not a special counsel or a congressional committee.

"You need a nonpartisan commission of experts, people who really can dig into this, people who really have experience and who don't have an agenda, who aren't finger-pointing," Dershowitz said.

He said that both Mueller and former FBI Director James Comey have helped turn the Russia investigation into a partisan issue.

"And Americans do not want to see indictments or impeachments based on partisan issues."
