Last month, Brennan Center attorneys Katherine Yon Ebright and Leah Tulin, and I submitted an amicus brief in the Fifth Circuit case of W.M.M. v. Trump, opposing the Trump Administration's use of the Alien Enemies Act of 1798 as a tool for peacetime detention and deportation of immigrants. Katherine is a leading expert on the AEA and its history. The brief was filed on behalf of the Brennan Center for Justice at NYU, the Cato Institute, prominent law-of-war scholar Prof. John Dehn, and myself.
