On the day of Kate Steinle's funeral, Bill O'Reilly directed a message to the grieving family, saying that America let them down. 

"Kate was a vibrant, loving person, a generous American of whom we are all proud. The fact that she is no longer with us tonight is a travesty," said O'Reilly.

O'Reilly has highlighted this week the sanctuary city policies in San Francisco, where 32-year-old Steinle was shot to death last week by an illegal immigrant who had been deported five times.

The man charged with the murder, 45-year-old Francisco Sanchez, was in jail as recently as April 15, but local officials declined to prosecute. Federal authorities have said they were not notified by city officials of his release.

Earlier on Thursday, O'Reilly talked to Bill Hemmer to explain his petition for "Kate's Law," which would mandate a five-year federal prison sentence for illegal immigrants who are deported, but come back into the U.S. illegally.

"We, the undersigned, respectfully ask Congress to pass Kate's Law whereby undocumented aliens who are deported and return to the United States would receive a mandatory five year sentence in a federal penitentiary upon conviction," the petition reads

He said more than 200,000 people have signed the petition so far and predicted that Congress will pass the law.

"It's shocking that some Americans will not support Kate's Law, but you know the story: ideology is more important to some people than public safety," he said. 

O'Reilly called San Francisco Sheriff Ross Mirkarimi a "disgrace" for letting Sanchez out of jail, saying he's "so incompetent it's painful."

He argued that if Sanchez, a "low-level thug," can enter the country illegally six times, it shows how bad the border security situation has gotten. 

"That means anyone in the world can sneak into the country. That lowlife illegally crossed our border from Mexico six times? We don't have border enforcement. Does everybody understand that?"
