President Trump never really acknowledged President-elect Joe Biden's victory — or even mentioned his name after the election. But the president did leave a note for his successor before his Wednesday morning departure, outgoing White House Deputy Press Secretary Judd Deere told NPR.

Trump left the White House for the final time Wednesday morning, to the tune of some very fitting songs. Outgoing presidents and their staffs typically leave notes on their desks for their successors to aid in the transition and wish them well. But given Trump's history of not exactly following norms or accepting election results, it's a surprise that he followed that tradition.

It's unclear just what was in the note Trump left for Biden. In his farewell address, he did wish the next administration "great luck and great success," without mentioning their names. Outgoing Vice President Mike Pence, who reportedly did eventually offer his congratulations in a call to Vice President-elect Kamala Harris, also left behind a note for her.
