Ed O'Callaghan

Ed O'Callaghan is an American Republican lawyer, former co-chief of the terrorism and national security unit of the U.S. Attorney's office in New York, who resigned from the US Attorney's Office in July, 2008 to join John McCain's presidential campaign. One of three leaders of Sarah Palin's Alaska "truth squad," O'Callaghan became the public face of Palin's legal pushback against ethics charges related to her former brother-in-law, the so-called "Troopergate." In March 2009, the law firm Nixon Peabody announced that O'Callaghan had joined its Government Investigations and White Collar Defense Practice Group.
