official launch of his reelection campaign last night in orlando, florida. so let s go straight to florida where nbc s peter alexander is standing by. peter, this was a rerun, a repeat or, one could say, president trump s greatest hits. he seemed to focus more on past grudges than a vision for the future. reporter: yeah, stephanie, i think you re exactly right. it certainly in many ways did feel a lot like the 2016 campaign never ended for president trump, last night airing a lot of those familiar grievances, attacking those same familiar targets, his perceived enemies, hillary clinton, the media, the democrats, the establishment. one of the real challenges for the president this time around we saw last night who compared to being sort of an aging rock star, who was repeating those chants, build the wall, drain the swamp, all the familiar languages, reenergized the crowd going forward.
