Trump's quest for at least some portion of a wall along the U.S.-Mexico border is not over, however. Friday's agreement only temporarily reopens the government, providing a three-week period for Congress to negotiate a longer-term spending agreement. The president said he would continue advocating for his signature campaign promise and threatened to again shut down the government or declare a national emergency to use his unilateral powers to build the wall if Congress does not appropriate wall funding by Feb. 15.
