Robert Patrick Casey Jr. (born April 13, 1960) is an American attorney and politician serving as the senior United States Senator from Pennsylvania, a seat to which he was first elected in 2006. He previously served as Pennsylvania Auditor General from 1997 to 2005 and as Pennsylvania Treasurer from 2005 to 2007.
Born in Scranton, Pennsylvania, Casey is the son of Bob Casey, a former Governor of Pennsylvania. After graduating from Scranton Preparatory School in 1978, he attended the College of the Holy Cross. He received his J.D. degree from The Catholic University of America Columbus School of Law. Casey practiced law in Scranton, Pennsylvania, before beginning his political career as Pennsylvania’s Auditor General, a post to which he was elected in 1996 and re-elected in 2000.
In 2002, Casey attempted to follow in his father’s footsteps by running for Governor of Pennsylvania, but was defeated in the Democratic primary by eventual general election victor Ed Rendell. After being term-limited out of his position as Auditor General, Casey was elected Treasurer in the 2004 election.
Casey defeated two-term Republican incumbent Rick Santorum in the 2006 United States Senate election in Pennsylvania. He was reelected in 2012 and 2018, becoming Pennsylvania’s first ever Democrat to win a third consecutive term in the Senate.
