President Donald Trump's plan to deploy National Guard troops to the U.S. border with Mexico is in motion, with deployments coming as soon as Wednesday night, but otherwise, the administration has few details about the action.
A senior administration official, who spoke on condition of anonymity, reiterated much of what the administration had already announced about the plan but did not disclose how much it would cost or how long the mission would last.
When asked if there was a plan in place, a senior administration official said the discussion was by no means new.
"There have been ongoing conversations between DHS, DoD and the border states in regard to the mission that we will be supporting," the official said. "We are not going to DoD and saying we need X number of people; we are going to DoD and saying we need to fulfill this mission requirement, and DoD is working to identify and task that out."
