Watch: UN audience laughs as Trump boasts of America's might

President Donald Trump delivered a sharp rebuke of global governing at the United Nations on Tuesday, drawing headshakes and even mocking laughter from fellow world leaders as he promoted his aggressive "America First" agenda and boasted of America's economic and military might. Five sentences into the president's remarks, the audience began to chuckle and some leaders broke into outright laughter, suggesting the one-time reality television star's puffery is as familiar abroad as it is at home. Appearing briefly flustered, Trump smiled and joked that it was not the reaction he expected ``but that's all right.''
