Author Derek Hunter slammed Democrats for their recent negative and "dangerous" rhetoric against President Donald Trump and his administration.

Democrats have increasingly been vocal about battling back against the Trump administration after Rep. Maxine Waters (Calif.) called for her supporters to "absolutely harass" Trump administration officials in public.

The rhetoric continued after Supreme Court Justice Anthony Kennedy announced his retirement last week, which could give President Trump the opportunity to move the court solidly to the right.

Hunter, the author of "Outrage, Inc.," said that the left is "freaking out" over the potential Supreme Court pick and that it's funny to watch.

"They've been turning up the outrage meter to 11 on everything," he said. "They are at a point where you can't be more outraged anymore."

He added that the left first vowed to fight back against the president's decisions regarding the border crisis, then the Supreme Court's decision to uphold President Trump's travel ban, and now they're preparing for Trump's next pick for the court.

"Liberals need to keep people in a constant emotional state because in an emotional state, you're not thinking rationally." Hunter said. "Rational thought is kryptonite to the left."

He said that there will be more dangerous rhetoric spoken by Democrats, like filmmaker Michael Moore, who on "The Late Show" said that Democrats need to "get off the couch" and put their "bodies on the line" to protest Trump's policies.

"There's a level of insanity, and then there's Michael Moore," he said.
