Shadegg laughs at McCain's border fence ad

Rep. John Shadegg (R-Ariz.) couldn't contain himself Thursday when he saw footage of Sen. John McCain's (R-Ariz.) latest campaign ad.

The 2008 GOP presidential nominee is facing a tough primary challenge this cycle from former Rep. J.D. Hayworth (R) and has come out tough on border security.

But some say the position is a flip-flop for McCain, who during the Bush administration worked with Sen. Edward Kennedy (D-Mass.) on a comprehensive immigration reform bill that included a path to citizenship for illegals.

In the ad, the Arizona senator says that the state has to "complete the danged fence" along the Arizona-Mexico border. A sheriff walking with him responds, "senator, you're one of us."

In an appearance on MSNBC's "Morning Joe" Shadegg, who is retiring, could be seen laughing along with hosts Joe Scarborough, a former Republican congressman, and Mika Brzezinski.

After he composed himself, the congressman said, "It seems like some politicians have kind of changed ground on this issue. I guess maybe the president thinks it's funny. Senator McCain now doesn't think it's funny. And he's saying we've got to get tough on the border."
