Kristi Noem sending South Dakota National Guard to US-Mexico border

South Dakota is the latest state to send its residents to the U.S.-Mexico border to help overwhelmed federal and local law enforcement respond to sustained high levels of illegal immigration.

But unlike Nebraska and Florida, which sent state troopers and local police officers to Texas earlier this month, South Dakota Gov. Kristi Noem will send in the National Guard so as not to risk a decline in public safety in her state.
