Ann Coulter reacted on "Hannity" tonight to the news that an illegal immigrant has been charged with murdering a San Francisco woman.

According to Fox News, Francisco Sanchez, 45, is expected to be arraigned Tuesday in the killing of Kate Steinle.

Sanchez, a repeat drug offender who was deported from the U.S. five times, was released from jail on April 15. At the time, law enforcement officials declined to prosecute him. 

Coulter noted that violence by immigrants remains a bigger threat than an attack by ISIS.

She brought up another case in Texas, where an illegal immigrant who was deported four times murdered his wife with a hammer.

"We've all been warned all week: 'Watch out for ISIS. Watch out for ISIS this weekend.' And, no, instead Americans were killed by immigrants," said Coulter.

"The government is allowing people who have no right to be here into our country, whether legally or illegally," Coulter stated. "What's striking about the San Francisco story is that it happened in a place liberals might go."

Coulter said that politicians, like Chris Christie, continue to claim that a fence will not solve the border security problem.

"It's like saying buckets don’t work, of course fences work," she said.

"Americans aren’t stupid, why doesn’t Chris Christie say that to Israel or China because their fences work just fine," Coulter added. "And, you know, why don’t we just try a fence?"
