Kirsten Elizabeth Gillibrand (née Rutnik; /ˈkɪərstən ˈdʒɪlɪbrænd/ (About this soundlisten) KEER-stən JIL-i-brand; born December 9, 1966) is an American attorney and politician serving as the junior United States Senator from New York since 2009. A member of the Democratic Party, she previously served as a member of the U.S. Representative from 2007 to 2009.

Born and raised in upstate New York to two attorney parents, Gillibrand graduated from Dartmouth College and from the UCLA School of Law. After holding attorney positions in government and private practice and working on Hillary Clinton’s 2000 U.S. Senate campaign, Gillibrand was elected to the United States House of Representatives in 2006. She represented New York’s 20th congressional district, a conservative district in upstate New York, and was re-elected in 2008. During her House tenure, Gillibrand was a Blue Dog Democrat noted for voting against the Emergency Economic Stabilization Act of 2008 (commonly known as the bank bailout) and for supporting Medicare-for-all.

Following Senator Clinton’s appointment as Secretary of State in 2009, Governor David Paterson selected Gillibrand to fill the Senate seat that had been vacated by Clinton. Gillibrand won a special election in 2010 to keep the seat, and was subsequently reelected to full terms in 2012 and 2018. During her Senate tenure, Gillibrand has shifted to the left. She has been outspoken on sexual assault in the military and sexual harassment, having criticized President Bill Clinton and Senator Al Franken (both fellow Democrats) for sexual misconduct. She supports paid family leave, a federal jobs guarantee, and the abolition and replacement of the U.S. Immigration and Customs Enforcement.

On March 17, 2019, Gillibrand announced she is running for President in 2020.
