President Trump returned Saturday to campaign mode — holding a rally in a Florida airport hangar in which he again railed against the “dishonest media” and repeated his promises to build a “beautiful” border wall, replace “disastrous” ObamaCare and other familiar lines that rallied him to an unexpected White House win. The roughly 50-minute speech outside Melbourne, Florida, was quintessential Trump — with the president vowing to help disillusioned Americans find better jobs and live safer, while attacking the news media for unfavorable stories and calling it “a big part of the problem” toward his mission to “make America great again.”
