President Trump and White House officials pressed congressional Republicans on Sunday to use the looming threat of a government shutdown to win funding for a wall along the U.S.-Mexico border, a top priority for the administration as it nears the symbolic 100-day mark.

President Trump on Thursday morning released a $1.15 trillion budget proposal that seeks a major increase in military and other security spending while slashing spending in a wide range of other agencies including the EPA and State Department.
