A Thursday press conference with Donald Trump turned into an impromptu hearing, as questions from the media drifted to Democratic House Speaker Nancy Pelosi's claims that the president threw a "temper tantrum" when he called off a Wednesday meeting.Several top aides stepped forward during the presser to recount their own version of the events, with all of them supporting President Trump's version that he was "calm" while refuting claims by Pelosi and House Majority Leader Chuck Schumer that he was "yelling," "banging his fist on the table" or "throwing a temper tantrum."
