The New York Times reports:
An hour before Dr. Anthony S. Fauci threw the first pitch at the season opener between the New York Yankees and the Washington Nationals, President Trump stood on the briefing room stage at the White House and declared that he, too, had been invited to throw out his own opening pitch.
There was one problem: Mr. Trump had not actually been invited on that day by the Yankees, according to one person with knowledge of Mr. Trump’s schedule. His announcement surprised both Yankees officials and the White House staff.
But Mr. Trump had been so annoyed by Dr. Fauci’s turn in the limelight, an official familiar with his reaction said, that he had directed his aides to call Yankees officials and make good on a longtime standing offer from Mr. Levine to throw out an opening pitch. No date was ever finalized.
After Trump invented the offer, his staff rushed to tell him he was already booked that day, leading Trump to tweet from the golf course on Sunday that he would be too busy to deliver the pitch.
