South Dakota Gov. Kristi Noem (R) is deploying National Guard troops to Texas to help “secure” the U.S.-Mexico border, she announced Tuesday. 

The move comes as record numbers of people, mostly from Central America, seek asylum at the U.S. southern border. Republicans have seized on the border crossings in recent months, blaming President Biden and his administration for failing to adequately secure the border.

“The border is a national security crisis that requires the kind of sustained response only the National Guard can provide,” Noem, who’s seen as a potential 2024 presidential contender, said in a statement. 

“We should not be making our own communities less safe by sending our police or Highway Patrol to fix a long-term problem President Biden’s Administration seems unable or unwilling to solve.”

Noem’s office said that the initial deployment of as many as 50 South Dakota National Guard troops will last between 30 and 60 days and will be paid for with a private donation. It’s not clear yet what their mission will be, but Noem’s office said that state officials are working to finalize the details of the effort.
