I think Trump should call it off. The media is the enemy. He should ignore them and marginalize them to the greatest extent possible.
He can't.
Let's get with the program, folks.
The dinner is sponsored by the White House Correspondents' Association (WHCA) and is organized and financed by the association.
The White House has NOTHING TO DO WITH THE EVENT'S STRUCTURE ITSELF except for some peripheral matters such as consultation on the president's speech, special guests, security, etc.
