PIERRE, S.D. — A week after ordering up to 50 National Guard troops to Texas, backed by $1 million in funding from a Tennessee billionaire's donation, South Dakota Gov. Kristi Noem says she'll deploy an additional 125 guardsmen and women as part of a broader federal mission to secure the nation's southern border.

The shipment of troops came in an announcement on Wednesday, July 7. Noem said the state guard's 1742nd Transportation Company, currently stationed in Sioux Falls and Flandreau, would be sent from nine months to a year to be in a "federal pay status."

The notice from the governor's office says the soldiers will contribute "non-law enforcement support" to U.S. customs agents as part of a mission along the southwest border, from Texas west to California.

Already, 3,000 Guard members from various states are involved in a federal mission to the border to assist as the nation's border sees a surge of migrants and asylum seekers from Central and Southern America.

The newest troop deployment was in response to a request from the U.S. Department of Homeland Security and the National Guard Bureau. That's opposed to last week's request, which an email to legislators revealed came in response to a request by the Texas governor, and at the prompting of a private charity with a history of making GOP donations.

In a release, Noem called South Dakota's National Guard "the very best in the country."

"I am hopeful that this mission indicates the Biden administration is waking up to the devastating situation at the border," said a statement from the Republican governor.
