A Pennsylvania father and son were arrested Thursday for allegedly making harassing phone calls to the family of former Alaska governor Sarah Palin. Craig Christy, 47, and his son, Shawn, 19, of McAdoo, Pa., were also charged Wednesday in a federal indictment filed in Alaska with making harassing phone calls from Aug. 1 to Aug. 9, calls that were made after Palin obtained a restraining order against the two men. An Alaska state court issued a restraining order against Shawn Christy in September 2010, ordering that he have no further contact with Palin. He previously admitted in court to having threatened to rape Palin, sending her emails and gifts and traveling to Anchorage earlier this year. No bail was set for the pair, and they will be transported to Anchorage for further proceedings, the FBI said.
