Kristi Lynn Arnold Noem[1] (/noʊm/ NOHM;[2] née Arnold; born November 30, 1971) is an American politician serving as the 8th United States secretary of homeland security since 2025. A member of the Republican Party, she served from 2019 to 2025 as the 33rd governor of South Dakota and from 2011 to 2019 represented South Dakota's at-large congressional district in the U.S. House. She began her political career in the South Dakota House of Representatives, serving from 2007 to 2011.
Noem was the first female governor of South Dakota, elected in 2018 with the endorsement of President Donald Trump. She gained national attention during the COVID-19 pandemic for opposing statewide mask mandates and advocating voluntary measures. Noem has conservative positions on most domestic issues, particularly gun rights.
In addition to politics, Noem is a farmer and rancher. She has published two autobiographies, Not My First Rodeo: Lessons from the Heartland (2022) and No Going Back (2024), which sparked controversy for its account of her killing a young family dog and claims to have met with foreign leaders.
Noem and her family lived on their South Dakota ranch even during her tenure as governor.
