WHAT:

Fast Company - A group of three veterans and an architectural historian filed a separate lawsuit in federal court in Washington, D.C., claiming the project needs to be approved by Congress.

Fast Company - The judge in the veterans' lawsuit mandated that the administration must give the court 48 hours' notice before undertaking any activities related to or in preparation for construction of the arch.

Fast Company - The lawsuit claims that the National Park Service is proceeding "full-speed toward ground-disturbing construction" despite stating that a final decision has not been made.

Fast Company - The lawsuit alleges that the National Park Service's review process is a "pretext designed to shore up justifications for building the Arch in accordance with the President's repeated marching orders."

Fast Company - The Arlington County Board's lawsuit states that the project will have "severe, unique, and wide-ranging negative impacts" on the county and its residents.

CNN - Arlington County Board filed a lawsuit to stop the construction of President Trump's "Triumphal arch."
