Donald Trump plans "a major announcement" tomorrow in Nevada which "will pertain to the Presidential race," Politico reports.
Wall Street Journal: "Mr. Trump loves to keep people guessing -- and elbowing his way into the
headlines. Perhaps the best question, if he's not throwing his hat in
the ring, is whether the candidate who receives his endorsement actually
wants his backing."
Update: The New York Times reports Trump will endorse Newt Gingrich.
