WASHINGTON (AP) — The White House is opening a weeklong celebration of President Donald Trump’s first 100 days in office. Officials kicked off the promotional campaign Monday with a focus on his immigration crackdown. Tom Homan, Trump’s top border adviser, said “we’re going to keep doing it, full speed ahead.” Trump is holding a rally in Michigan on Tuesday and delivering a commencement address at the University of Alabama on Thursday. Although immigration remains the Republican president’s strongest issue in public opinion surveys, he’s faced declining support overall. Polling from AP-NORC shows there are concerns that he’s focused on the wrong issues.
