Noem lauded Rubio as a “next-generation conservative leader that puts our party in the best position to win back the White House,” and said he stands above the crowded field of GOP contenders for his “ability to articulate a conservative vision for what kind of country we can become in this new American century.”

"As the son of a bartender and a maid, he possesses a personal understanding of the challenges facing hardworking taxpayers in South Dakota and across the country, and he has conservative solutions to help address today's most pressing problems," Noem said in a statement.

It’s the latest sign that establishment Republicans are gravitating towards Rubio.

Last week, Rubio won the backing of influential Republican billionaire Paul Singer over former Florida Gov. Jeb Bush.

Half of Bush’s House supporters are from Florida, where he has deeper political ties than Rubio from his time as governor.
