Tulsi Gabbard (; born April 12, 1981) is an American politician and military officer serving since 2025 as the 8th director of national intelligence (DNI). She has held the rank of lieutenant colonel in the U.S. Army Reserve since 2021, and previously served as U.S. representative for Hawaii's 2nd congressional district from 2013 to 2021. A former Democrat, she joined the Republican Party in 2024. Gabbard was the youngest state legislator in Hawaii from 2002 to 2004.

Gabbard joined the Hawaii Army National Guard in 2003 and was deployed to Iraq from 2004 to 2005, where she served as a specialist with the medical unit, and received the Combat Medical Badge. In 2007, Gabbard completed the officer training program at the Alabama Military Academy. She went to Kuwait in 2008 as an Army Military Police officer. In 2015, while also serving in Congress, Gabbard became a major with the Hawaii Army National Guard. In 2020, she transferred to the U.S. Army Reserve and was promoted to the rank of lieutenant colonel in 2021.

In 2012, Gabbard was elected to the U.S. House of Representatives from Hawaii's 2nd congressional district. She became the first Samoan American and Hindu American member of U.S. Congress. During her tenure in Congress, she served on the House Armed Services Committee (HASC), where she introduced several bills related to veteran issues. Gabbard also served on House Foreign Affairs Committee. She supported the military campaign to defeat Islamic extremism but opposed the U.S. intervention in the Syrian civil war. In her fourth term, Gabbard served on the HASC Subcommittee on Intelligence, which oversaw military intelligence and counterterrorism.

Gabbard launched her 2020 presidential campaign running on an anti-interventionist and populist platform but dropped out and endorsed Joe Biden in March 2020. Previously, she also served as vice-chair of the Democratic National Committee (DNC) from 2013 to 2016 but resigned to endorse Bernie Sanders for the 2016 Democratic presidential nomination. After her departure from Congress in 2021, Gabbard took stances on issues such as abortion, foreign policy, border security and transgender rights that differed significantly from her former Democrat colleagues. She left the Democratic Party in 2022.

In 2024, Gabbard endorsed Donald Trump for the presidential election and joined the Republican Party later that year. After Trump nominated Gabbard for DNI, her past statements on Syria and the Russian invasion of Ukraine drew scrutiny and concern. Many veterans and Republicans defended Gabbard's record, noting her military service and Congressional experience. In February 2025, she was confirmed by the Senate, becoming the highest-ranking Pacific Islander American government official in U.S. history. Gabbard is the youngest person to serve as DNI and the first millennial to hold the office.
