Excellent move indeed.
Trump should announce a large donation to the relief fund while there.
Trump will come up with something—listen to what is happening is best—show he cares—he has done this in the past. He is starting to act like a president, holding a “cabinet” Meeting, being Briefed, now visiting a disaster area. All he needs is to meet with community leaders for half hour, give a short talk, and be photographed at some flooded places and greet for flood victims. Maybe organize a fund raiser to help the folks. I think he will do some good—more than Obama—who isn’t even there.
