Thurmond left the Senate in January 2003 as the United States' longest-serving senator, a record later surpassed by Senator Byrd. In his November farewell speech in the Senate, Thurmond told his colleagues "I love all of you, especially your wives," the latter being a reference to his flirtatious nature with younger women. At his 100th birthday and retirement celebration in December, Thurmond said, "I don't know how to thank you. You're wonderful people, I appreciate you, appreciate what you've done for me, and may God allow you to live a long time."
