Giuliani and Thompson in Gun Battle

Former New York City Mayor Rudy Giuliani's campaign took aim at Fred Thompson, after the former senator posted a blog on his Web site criticizing New York City gun-control laws and singling out Giuliani by name.

"When I was working in television, I spent quite a bit of time in New York City,” Thompson wrote, according to The Hill newspaper. "There are lots of things about the place I like, but New York gun laws don’t fall in that category.

"Now, the same activist federal judge from Brooklyn who provided Mayor Giuliani’s administration with the legal ruling it sought to sue gun makers, has done it again. Last week, he created a bizarre justification to allow New York City to sue out-of-state gun stores that sold guns that somehow ended up in criminal hands in the Big Apple.”

Giuliani’s campaign reacted on Tuesday:

"Those who live in New York in the real world - not on TV - know that Rudy Giuliani’s record of making the city safe for families speaks for itself,” Katie Levinson, Giuliani's communications director, said in response to press questions. "No amount of political theater will change that.”
