U.S. Sues Arizona Over Shipping Containers Along Mexico Border

The White House is suing Arizona Governor Doug Ducey to prevent him from filling border wall gaps with shipping containers, a strategy to curb illegal crossings. The makeshift wall is on federal land, leading to a trespassing claim. Ducey, leaving office soon, has agreed to remove the containers but only according to the White House's timeline.

What is the timeline for Governor Ducey leaving office?

What promise has Governor Ducey made regarding the shipping containers?
