Tucker Carlson faced off with a liberal radio host over an ACLU ad that compares Supreme Court nominee Judge Brett Kavanaugh to Bill Clinton, Bill Cosby and other powerful men who have faced allegations of sexual misconduct.

Kavanaugh's confirmation to the high court has been thrown into doubt due to a series of sexual assault allegations that he has emphatically denied.

Carlson lamented that the ACLU -- which was founded to defend civil liberties like free speech and due process -- has joined the "tide of derangement" on the left in opposing Kavanaugh.

"They are now running an ad declaring Kavanaugh guilty without the need for a trial or in fact any evidence," Carlson said.

Chris Hahn, syndicated radio host and former aide to Sen. Chuck Schumer (D-N.Y.), said the debate over Kavanaugh isn't necessarily about the judge's guilt or innocence on the sexual assault allegations, but if he's been truthful in his hearings before the Senate Judiciary Committee.

Hahn noted that Supreme Court justice is a lifetime appointment, saying that many people "feel in [their] heart" that Kavanaugh may indeed have engaged in sexual misconduct or not been truthful with the committee.

"The standard is if you 'feel in your heart?'" Tucker asked. "So if I feel in my heart that you're a child molester -- I don't have an actual evidence -- can I start telling people that on TV? And see how it affects your family, and how it affects your employment, what your kids think of it."

He asked Hahn if he wants to live in a world where feeling something in your heart is enough to "systematically destroy" someone and their family.

"You're saying yes because it's so important because abortion or whatever," Carlson said. "But is that a standard you really want to live under?"
