Fred Thompson didn't pull any punches against Rudy Giuliani today, in response to a question about illegal immigration during a Georgia campaign stop.

"I voted to do away with sanctuary cities in 1996," he said of his time in the Senate. "At about that same time, Mayor Giuliani was supporting the concept of sanctuary cities."

As for Romney, Thompson essentially called him a Johnny-come-lately on the issue: "Governor Romney certainly didn’t say anything against sanctuary cities until recently."
