NEW YORK, April 23 (Reuters) - U.S. stocks turned volatile on Tuesday, sharply cutting gains for a few minutes and then bouncing back, after a "bogus" Associated Press report about explosions at the White House.
An AP tweet, which an AP spokesman says was "bogus," had said there were two explosions at the White House.
