US House and Senate career of John McCain (until 2000)

John Sidney McCain III retired from the United States Navy in April 1981. His last four years in the service had been spent as the Navy's liaison to the United States Senate. He moved to Arizona with his new wife and, aided by a job from his father-in-law and the contacts it gave him, soon began a new career in politics.

In 1982, he was elected as a Republican to the U.S. House of Representatives from Arizona's 1st congressional district. After serving two terms there and making an impression as a rising political figure, he was elected U.S. Senator from Arizona in 1986. He became one of the senators entangled in the Keating Five scandal of the late 1980s, but survived it and was re-elected in 1992 and 1998.

While generally adhering to American conservatism, McCain established a reputation as a political maverick for his willingness to defy Republican orthodoxy on several issues. In reaction to his Keating Five experience, he made campaign finance reform one of his signature concerns. He was also a leader in normalizing diplomatic relations with Vietnam. His national visibility as a senator gave him the basis to begin a campaign for the 2000 Republican nomination for President of the United States.
