The news that Trump decided to leave a letter on Biden’s desk came as a surprise to many, considering that there were reports from several news outlets he wouldn’t partake in the same traditions that other presidents participated in.
For starters, it became known shortly after the electoral votes were officially counted that Trump didn’t plan on attending Biden’s inauguration ceremony and would instead depart from the Oval Office before the ceremony.
He also didn’t arrange a personal visit with Biden and his wife, as is par-the-course between past presidents, and Melania didn’t meet with Dr. Jill Biden to give her a tour of the White House, a longstanding tradition between First Ladies.
The only “passing of the torch” tradition that Trump did partake in, it seems, was the customary letter from president to president.
