Trump Administration Plans To Divert Additional $3.8B For Border Wall

The transcript discusses the U.S. government's plan to divert $7.2 billion in military funding for the U.S.-Mexico border wall, in addition to $2 billion requested from Congress. The administration has already redirected $6.7 billion but claims $18 billion is needed for 1000 miles of barrier. Republican Representative Mac Thornberry argues that funding should come from the Department of Homeland Security, not the Defense Department, as it undermines Congress's authority. President Trump extended the national emergency on the southern border for another year to fund the wall.
