Republican Kristi Noem deploys national guard to Texas

Move justified as response to crimes' committed by migrants

South Dakota's Republican governor, Kristi Noem, is deploying up to 50 national guard troops to the southern US border, responding to a call from the Texas governor, Greg Abbott, for help dealing with a rise in border crossing, although the majority of migrants have been sent back to Mexico.

Noem said on Tuesday in a statement that she was responding to his request for assistance in responding to ongoing violations of state and federal law by illegal aliens crossing the unsecured border".
