On this day....
1950: Congress overrides President Truman's veto and passes the McCarran Internal Security Act, requiring registration of members of groups the Attorney General determines to be Communist fronts, and establishing of emergency concentration camps. Truman called the act "the greatest danger to freedom of speech, press, and assembly since the Alien and Sedition Laws of 1798." Portions of the Act allowing exclusion of gays and lesbians from the U.S. are still on the books, and enforced at the borders.
