As you can see in the picture above, we've talked with Rep. Lou Barletta of Pennsylvania a number of times on the show about the issue of illegal immigration. We last crossed paths in Washington D.C. as part of this year's Hold Their Feet to the Fire event.

The Congressman joined the show today to talk about his Mobilizing Against Sanctuary Cities Act, which is meant to stop all federal funds from flowing to states or localities which resist or ban enforcement of federal immigration laws, or flatly refuse to cooperate with immigration officials. In short, sanctuary cities.

The legislation follows the July 1st San Francisco murder of 32-year-old Kate Steinle, whose accused killer is a seven-time felon who had been deported five times previously.  As the Congressman tells us, he has personal experience with a similar crime, as he was mayor of Hazleton when a local man, Derek Kichline, was murdered by an illegal immigrant who had also been released by a sanctuary city.

We discuss whether or not GOP leadership in the House will allow a vote on the measure and the similar effort that's taking shape in the U.S. Senate. Here's our full interview with Rep. Lou Barletta:
