President Donald Trump is facing challenges on Capitol Hill and in the courts over his emergency declaration, which would let him transfer funds from other construction accounts to pay for his long-desired wall along the border between the U.S. and Mexico.
Trump wanted Congress to appropriate $5.7 billion for the barrier, but in a fiscal 2019 spending bill enacted Feb. 15, lawmakers provided only $1.375 billion, limited to “pedestrian fencing” such as steel bollards.
