Bill O'Reilly spoke to Anna Kooiman on "Fox and Friends Weekend" about the dangers of liberal sanctuary city policies and his petition for the creation of "Kate's Law," which would impose a five-year federal prison sentence on illegal immigrants who are deported and reenter the U.S. illegally.

O'Reilly said that many illegal immigrants are hardworking people who are simply looking for better lives for their families, but along with those people comes a dangerous, criminal element.

"The sanctuary city people refuse to separate the two," O'Reilly stated. "So therefore, Kate Steinle, 32-years-old, winds up murdered by a guy who snuck in here six times. And yet they still won't do anything about it. So I have to."

O'Reilly explained that under "Kate's Law," Steinle's murderer, Francisco Sanchez, would have been harshly punished for illegally entering the U.S. multiple times and would have been serving life in prison.

"The Factor" host also slammed the "blame game" that's going on in San Francisco following Steinle's murder, which includes the sheriff, the mayor and city supervisors.

"They’re all dishonest, corrupt people across the board," O'Reilly said. "But it’s easy to bash San Francisco and the other sanctuary cities. What’s wrong with Congress? 30 years, 30 years, they’ve done nothing."
