After canceling her planned speech at the University of California-Berkeley, conservative commentator Ann Coulter will sit down with Sean Hannity tonight to discuss the controversy surrounding the event.

The speech was originally scheduled to take place Thursday – but Berkeley asked to postpone it until next month amid threats of violent protests.

Coulter had vowed to speak at a public square at the university on Thursday, but that will no longer be happening.

Coulter told FoxNews.com that the event was canceled after Young America’s Foundation, a conservative youth organization, pulled its support.

“I looked over my shoulder and my allies had joined the other team,” Coulter said.

She blasted the "censorship" in a string of tweets...

I’m so sorry Berkeley canceled my speech. I’m so sorry YAF acquiesced in the cancelation. And I'm so sorry for free speech crushed by thugs. — Ann Coulter (@AnnCoulter) April 26, 2017

I’m so sorry Berkeley had a different story every 20 minutes, which always was: No speech. — Ann Coulter (@AnnCoulter) April 26, 2017

If we had continued to fight we would have won. — Ann Coulter (@AnnCoulter) April 26, 2017

I’m very sad about Berkeley's cancelation, but my sadness is greater than that. It is a dark day for free speech in America. — Ann Coulter (@AnnCoulter) April 26, 2017

It’s sickening when a radical thuggish institution like Berkeley can so easily snuff out the cherished American right to free speech. — Ann Coulter (@AnnCoulter) April 26, 2017

I am so grateful to people like Bill Maher, Chris Matthews and Margaret Carlson for opposing Berkeley’s censorship. — Ann Coulter (@AnnCoulter) April 26, 2017

Don't miss the must-see interview tonight on Hannity at 10:00 p.m. ET on Fox News Channel. Plus, hear from Newt Gingrich and TMZ's Harvey Levin, who is calling out the media's anti-Trump coverage.
