Trump's schedule has gotten increasingly opaque over the past two months. It's rarely clear what the President is doing on any given day unless he's scheduled a media appearance or an official visit with a foreign leader.
The White House hasn't confirmed it but the Los Angeles Times reports that today he will meet with the head of the International Olympic Committee. Los Angeles is hoping to hose the 2024 or 2028 Olympics.
Trump will also host the congressional picnic at the White House.
