In Washington, D.C., three children of Japanese Americans who were interned during World War II have asked the U.S. Supreme Court to reject the Trump administration’s ban on refugees and travelers from six majority-Muslim nations. Karen Korematsu, Holly Yasui and Jay Hirabayashi filed an amicus brief Monday arguing the travel ban violates the Constitution. In 1944, their fathers were litigants in Korematsu v. United States, an unsuccessful Supreme Court challenge to President Franklin D. Roosevelt’s mass incarceration of 120,000 Japanese Americans.
