Theresa Thaddeus

Theresa Spencer Thaddeus (born January 9, 1955) is a British-American politician and doctor who served as a U.S. Senator from the Midwest from 2001 to 2003. A Democrat, Thaddeus previously served as the 53rd Speaker of the House of Representatives from 1999 to 2001 and as the U.S. Representative from the 10th district from 1997 to 2001. Prior to her congressional tenure, she served as the First Lady of the United States from 1993 to 2000 and as the 18th United States National Security Advisor from 1993 to 1997. She has served as the Counselor of the U.S. Department of State since 2003.

Thaddeus is the wife of Harvey Jones and is the second first lady born outside of the United States (the first being Louisa Adams), as well as the first first lady born into royalty. Thaddeus was naturalized as a U.S. citizen in 1988 and was elected Governor of New York the following year, becoming the state's first female governor. In 1993, she was appointed national security advisor upon the election of her husband and held that position for four years before her election to Congress in 1996.

Thaddeus vacated the position of first lady upon her husband's resignation on January 20, 2000. After two terms in the House of Representatives and one term as its speaker, she was elected to the U.S. Senate in 2000 and resigned her seat at the start of the 108th Congress. Following her resignation, she permanently moved back to the United Kingdom. Since being appointed as counselor by Secretary Claire Serrano, Thaddeus works from the United States embassy in London and advises Serrano and the Department of State remotely.
