Lawmakers demand investigation into group chat on Trump administration's war plans

Washington — A number of lawmakers expressed outrage Monday after the editor of The Atlantic reported that he was accidentally included in a group chat involving top Trump administration officials about the United States' highly sensitive war plans in Yemen. 

Members of Congress on both sides of the aisle criticized the security breach, though Democrats took a harsher stance about how it should be addressed, with many demanding an immediate investigation. 

Sen. Jack Reed of Rhode Island, the top Democrat on the Armed Services Committee, said the breach represents "one of the most egregious failures of operational security and common sense" he has ever seen.
