Rehnquist married Natalie Cornell, whom he had met during his law school years, after his completing his clerkship. He also moved to Phoenix, Arizona to work for a law firm there. Rehnquist chose Phoenix for its pleasant weather and favorable political leanings. The next few years passed uneventfully for Rehnquist. He, together with his wife, raised a son and two daughters. Following advice given to him by Justice Felix Frankfurter, Rehnquist began his participation in the Republican Party. He became a Republican Party official and achieved prominence in the Phoenix area as a strong opponent of liberal initiatives such as school integration. Rehnquist campaigned for Republican presidential candidate Barry Goldwater during the 1964 elections. During that time, he befriended Richard Kleindienst, another attorney from Phoenix. When Richard Nixon rose to the presidency a few years later, he appointed Kleindienst deputy attorney general of his administration. Kleindienst sought Rehnquist for the position of deputy attorney general in the Justice Department's Office of Legal Counsel. When Justice John Marshall Harlan retired in 1971, the Nixon administration chose Rehnquist as Harlan's replacement. A Democratic Senate overwhelmingly confirmed his nomination. On January 7, 1972, Rehnquist -- and fellow nominee, Lewis Powell -- took their oaths of office.
