Sen. John McCain (R-Ariz.) expressed concern on Tuesday for his pal Snooki Pallozzi after the "Jersey Shore" star was arrested last week for disorderly conduct on a Seaside, N.J., public beach. The senator was speaking to a radio host of KTAR Radio in Arizona, who asked McCain what his thoughts were on Snooki's arrest. The raunchy reality star was held in jail for a few hours, then released.
