President Donald Trump takes the stage on Friday at an annual conservative forum, looking to plant his personal stamp firmly on the political movement even as some activists fret his immigration and trade policies go too far. Trump will address the third day of the Conservative Political Action Conference, or CPAC, which has focused on how to fulfill long-held Republican goals to revamp the U.S. tax code, repeal federal regulations on industry and repeal former Democratic President Barack Obama’s healthcare law.
