The House urged a speedy U.S. investigation of former U.N. Secretary General Kurt Waldheim, which could lead to barring his entry into this country. Acting on a voice vote without dissent, the non-binding resolution urged Atty. Gen. Edwin Meese III to decide quickly whether Waldheim should be placed on a "watch list" of foreigners to be denied visas. Rep. Romano L. Mazzoli (D-Ky.), chairman of the Judiciary subcommittee on immigration, said panel members agreed to forgo full hearings because "time was of the essence." Waldheim, who is accused of covering up a Nazi past, is the frontrunner in the final round of Austria's presidential election June 8.
