After his military service, Specter earned his law degree from Yale Law School. He entered private practice, co-founding a firm with Marvin Katz. In the early 1960s, he served as an assistant counsel for the Warren Commission. In this capacity, he helped develop the single-bullet theory, which posited that one projectile caused non-fatal wounds to both John F. Kennedy and Governor John Connally. This work served as a foundational element of the commission's investigation into the presidential assassination.
Philadelphia District Attorney
Specter began his political career as an assistant district attorney from 1959 to 1964. In 1965, he sought the office of District Attorney of Philadelphia. Though he started as a Democrat, he switched his registration to the Republican Party to mount his successful campaign against the incumbent, James C. Crumlish Jr. He held the position of District Attorney for eight years, serving two terms until 1974.
Senate Career and Party Affiliation
After unsuccessful attempts to gain higher office in the 1970s, Specter won election to the United States Senate in 1980. Over his thirty-year tenure, he served in various capacities, including time as Chair of the Senate Judiciary Committee from 2005 to 2007. Throughout his time in Washington, D.C., he maintained a moderate political profile. In 2009, he shifted his party affiliation from Republican back to the Democratic Party. He left the Senate in 2011 following his defeat in the 2010 Democratic primary.
