Ann Coulter will speak at the University of California, Berkeley next week, after the state-funded university initially canceled a public appearance she was set to make there. Berkeley changed its mind after coming under fire from free speech advocates across the political spectrum, instead inviting the conservative commentator to speak in May.

“Not agreed!” Coulter tells Moneyish, noting that that was during finals week at the university. “I can’t make it and did not agree to speak [on that date.] Dozens of people including me, my security and reporters have already booked flights and hotels for the speech on the 27th.”

Coulter been invited to opine on immigration by Berkeley College Republicans and the Young America’s Foundation, a group for young conservatives. She says she had agreed to numerous demands that the university typically doesn’t make of liberal speakers on campus. These included giving the speech during class hours and checking the IDs of attendees to make sure only university-affiliated personnel were present. “Berkeley canceled anyway!” she tells us.

Historically a hotbed of political conflict—just think back to Vietnam War-era protests—Berkeley has been in the headlines again recently. A February speech there by the alt-right provocateur Milo Yiannopoulos was canceled after violent protests, leading the President of the United States to chime in.

Coulter provided Moneyish with a letter that a legal representative for the College Republicans and Young America’s Foundation is sending to Berkeley today, in which the organizations threaten to sue the university. “The University’s actions violate fundamental principles of free speech…guaranteed by the United States Constitution, and will not be tolerated,” attorney Harmeet K. Dhillon wrote. He added that Berkeley had essentially given hecklers a veto over who could speak at the public school.

The conservative author had a typically acerbic response to what she called “fascistic opposition” cheering on the school: “Grow up!”
