After several days of back-and-forth between Ann Coulter and UC Berkeley, the conservative speaker's planned April 27 speech has been canceled after losing support from the conservative groups sponsoring her appearance, the New York Timesreported.

Her talk was canceled amid concerns over threats of violence at Berkeley.

Coulter, along with the Berkeley College Republicans, BridgeUSA and Young America's Foundation -- who organized and supported her appearance -- had taken a hard stand on the event happening as planned Thursday, with or without university support.

So much so that the conservative organizations filed a lawsuit Monday against the university, demanding accommodations to be made for the event Thursday. The lawsuit also argued that free speech was in danger.

The American Civil Liberties Union of Northern California agreed that Berkeley's efforts to move the speech to another date amounted to an attempt to block free speech.

But as of yesterday, the conservatives' support began to falter. YAF pulled support from Coulter, out of concern of violence, saying they would not risk the safety of their staff or students for her event. The Berkeley College Republicans and BridgeUSA also voiced concerns about threats of violence coming from both leftist and rightist groups.

There was some confusion yesterday about whether a space would be provided for her to talk on campus or whether the event would be moved off-campus.

This morning, UC Berkeley Chancellor Nicholas Dirks issued a statement indicating concern over expected violence.

Earlier this morning, Coulter reiterated her intention to speak tomorrow as planned.

Coulter apparently told BuzzFeed News that she wasn't responsible for the ultimate decision to cancel the talk.

USA TODAY College has reached out to the Berkeley College Republicans and YAF for comment and has not yet received a response.
