The Republican governor of Nevada has stated his opposition to President Donald Trump’s strategy of deploying National Guard troops to the U.S.-Mexico border.

In a Friday email, a spokeswoman for Gov. Brian Sandoval said that Sandoval does not view the deployment of members of the National Guard to the border to be “an appropriate use” of the troops.

The Hill reported: Defense Secretary James Mattis signed a memo Friday authorizing the National Guard to deploy up to 4,000 troops to the border.

Trump had announced last week that the military would send troops to defend the southern border until his border wall was completed. The White House later clarified that the National Guard would be sent to the border.

Arizona and Texas have both stated that they will send troops to the border starting this weekend.

Oregon Gov. Kate Brown (D) vowed Thursday to reject the request to send National Guard troops to the border.
