Democratic Gov. Tony Evers on Monday ordered Wisconsin National Guard troops assisting with security at the southwest border to return home, an executive order immediately drawing criticism from Republicans.

About 112 Wisconsin National Guardsmen currently serve in Arizona, according to an announcement from the Democratic governor’s office Monday. Evers said the responsibility in keeping borders safe and crime-free belongs to the U.S. Customs and Border Patrol.

“There is simply not ample evidence to support the president’s contention that there exists a national security crisis at our southwestern border,” Evers said in a statement. “I cannot support keeping our brave service men and women away from their families without a clear need or purpose that would actively benefit the people of Wisconsin or our nation.”

President Donald Trump in April directed the Department of Defense to support the Department of Homeland Security’s efforts to secure the Mexican border.
