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 law degree from the Columbus School of Law at The Catholic University of America. 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, becoming the first Democrat to win re-election to the U.S. Senate from Pennsylvania since Joseph S. Clark Jr. in 1962. In 2018, Casey defeated Republican U.S. Representative Lou Barletta to win a third term, becoming Pennsylvania's first ever Democrat to win a third consecutive term in the Senate.
On March 28, 2008 Casey announced his endorsement of frontrunning candidate Senator Barack Obama in the Democratic Party presidential primary. The Pennsylvania Report said that he "struck gold" by endorsing Obama early in the 2008 Democratic presidential primary, a move that gave him "inside access to the halls of the White House". Casey campaigned across Pennsylvania in support of Obama's candidacy in the months leading up to the primary in that state; they bowled together at Pleasant Valley Lanes in Altoona.
Casey has been described as an "even-keeled moderate, not only in tone but in policy", but since Donald Trump entered the White House, Casey has developed a "new, saltier social media prowess". Casey's outspoken opposition to many of Trump's actions has prompted one local media outlet to describe his new strategy before his 2018 re-election campaign as: "Oppose Trump every chance he gets."
In February 18, 2018, speaking to John Catsimatidis on New York radio station WNYM Bob Casey Jr. issued a warning to special counsel Robert Mueller not to deliver a report on his findings in the Russian interference in the 2016 United States elections investigation, too near to the 2018 midterm elections. While saying he could not "make any assumptions about where the Mueller investigation is going", he stated that he "would recommend Mueller not release a report on his findings near the midterms", because it would "distract from elections or cause people to question the election's integrity".
