ORLANDO, Fla. — President Donald Trump jabbed at the press and poked the political establishment he ran against in 2016 as he kicked off his reelection campaign with a grievance-filled rally focused more on settling scores than laying out his agenda for a possible second term. Addressing a crowd of thousands at Orlando’s Amway Center on Tuesday night, Trump complained he was “under assault from the very first day” of his presidency by a “fake news media” and an “illegal witch hunt” that had tried to keep him and his supporters down. He painted a disturbing picture of what life would look like if he loses in 2020, accusing his critics of “un-American conduct” and saying Democrats “want to destroy you and they want to destroy our country as we know it.” “A vote for any Democrat in 2020 is a vote for the rise of radical socialism and the destruction of the American dream,” he said.
