Noem's Cabinet appointment will make a plain-spoken rancher South Dakota's new governor

South Dakota Gov. Kristi Noem built a national profile during the COVID-19 pandemic, had fellow Republicans buzzing about her future, and published two political memoirs in three years. Lawmakers describe the man set to replace her as a friendly, plain-spoken rancher and specialty welder whom they expect to focus more on issues within the state.

Lt. Gov. Larry Rhoden's biggest — and fleeting — brush with national fame came in 2017 when he triggered a panic alarm during a hearing to test how quickly police would arrive to support his argument that people should be allowed to carry guns in the Capitol.

He's now receiving bipartisan praise as a South Dakota-focused conservative well-versed in how the state's Republican-dominated Legislature works.

President-elect Donald Trump announced Tuesday he would nominate Noem, 52, as the next U.S. homeland security secretary. If the Senate confirms Noem, Rhoden would automatically become governor. It's unclear how quickly that could happen.
