Doar was a legendary public servant and leader of federal efforts to protect and enforce civil rights during the 1960s. He served as Assistant Attorney General in charge of the Civil Rights Division of the Department of Justice. In that capacity, he was instrumental during many major civil rights crises, including singlehandedly preventing a riot in Jackson, Mississippi, following the funeral of slain civil rights leader Medgar Evars in 1963. Doar brought notable civil rights cases, including obtaining convictions for the 1964 killings of three civil rights workers in Neshoba County, Mississippi, and leading the effort to enforce the right to vote and implement the Voting Rights Act of 1965. He later served as Special Counsel to the U.S. House Committee on the Judiciary as it investigated the Watergate scandal and considered articles of impeachment against President Nixon. Doar continues to practice law at Doar Rieck Kaley & Mack in New York.
