Kate was born into a long line of Navy Servicemen; along with her mother, she moved around from base to base as her father was posted. Eventually she would join the navy and later become a CIA agent. She would go on to marry and divorce multiple times, as of 2006 one of her ex-husbands resided in Florida. (Ninety Miles Away) The other works for the state department.
In 1995 Harper was sent to Florida to observe talks about the removal of the American trade embargo on Cuba led by Leo McGarry. There she witnessed Leo's (who was then Secretary of Labor) alcoholism in full effect. She prevented him from getting in the driver's seat and decided to drive him to wherever he was going. (Ninety Miles Away)
Politically, Kate Harper seems to be less liberal than most of the White House staff. On the Election Day in 2006, she declared she did not "live and die for the Democratic Party" and strongly implied that she had voted for the Republican candidate Arnold Vinick.
She was present at the dedication of the Bartlet Library. President Bartlet comments that he 'read her book,' and complimented her prose. Given her area of expertise, it is likely the book was foreign policy commentary.
