The governor announced the mobilization on Twitter and said he was working closely with the defense and homeland security departments. More details are expected to come from the state guard.
The announcement comes two days after President Donald Trump said he wanted to deploy the military along the border with Mexico.
But specifics are still murky. The governor hasn’t said which part of Arizona’s 370 miles of border the guards will be stationed in. And the length of deployment is also unclear.
President Trump has said he wants the guard at the border until a border wall is built, and he called for 2,000 to 4,000 troops to be mobilized. California governor Jerry Brown is the only border governor so far to not commit to sending guard soldiers. Texas governor Greg Abbott and New Mexico governor Susana Martinez have both announced they will be sending troops but haven't given any specifics. Brown's office released a statement Thursday that his office was waiting for specifics from the White House.
Ducey spokesman Daniel Scarpinato said he had no details on what the troops would be assigned to do. In previous border deployments, Arizona troops did border watch missions, supported border wall construction and helped with administrative and other support tasks.
