President-elect Donald Trump will nominate South Dakota Gov. Kristi Noem to serve as the next homeland security secretary, two sources familiar with the decision said on Tuesday, choosing a staunch ally who has little experience on the national security stage.

Noem, once seen as a possible running mate for Republican Trump, is currently serving her second four-year term as South Dakota’s governor after a landslide reelection victory in 2022. She rose to national prominence after refusing to impose a statewide mask mandate during the COVID-19 pandemic.
