Like every nation, the United States has a right and a duty to secure its borders and protect its people against threats. But building a massive wall that spans the entire southern border is not a serious policy solution. It is a waste of money that diverts attention from genuine threats to our homeland security. My Administration is committed to ensuring that the United States has a comprehensive and humane immigration system that operates consistently with our Nation’s values. In furtherance of that commitment, I have determined that the declaration of a national emergency at our southern border in Proclamation 9844 of February 15, 2019 (Declaring a National Emergency Concerning the Southern Border of the United States), was unwarranted. It shall be the policy of my Administration that no more American taxpayer dollars be diverted to construct a border wall. I am also directing a careful review of all resources appropriated or redirected to construct a southern border wall.
