President Trump left a note for President-elect Joe Biden before departing the White House for a final time on Wednesday, a White House official confirmed.

There are no details yet on what the note says. The move keeps with a presidential tradition, despite Trump’s decision to buck other precedents with his exit on Wednesday.

Biden will receive the note when he heads to the White House later Wednesday after being sworn in as the 46th president of the United States in a ceremony at the U.S. Capitol.

Trump left Washington, D.C., Wednesday morning without plans to attend Biden’s inauguration later that day. 

Instead, he thanked his family and aides in a farewell speech from Joint Base Andrews and remarked a final time about his administration’s agenda before leaving office. Trump briefly wished the incoming administration luck, but did not mention Biden by name. 

“I will be watching, I will be listening, and I will tell you that the future of this country has never been better,” Trump told a group of supporters, aides and family members. “I wish the new administration great luck and great success. I think they will have great success. They have the foundation to do something very spectacular.” 

Trump is headed to his Mar-a-Lago club in Palm Beach, Fla. He took Air Force One there in his final hours as president.

Trump never called Biden or met with him following his election victory. Following the election, Trump contested the results and claimed that they were tainted by widespread voter fraud.

Trump earlier this month finally acknowledged that a new administration would take over on Jan. 20 after a mob of his supporters stormed the Capitol in an effort to stop the counting of Electoral College votes confirming Biden’s win.

First lady Melania Trump also bucked tradition by not hosting incoming first lady Jill Biden for a “tea and tour” at the White House to mark the transition of power.

While the Trumps will not attend the inauguration of Biden and Vice President-elect Kamala Harris, outgoing Vice President Pence and second lady Karen Pence will be on hand for the ceremony, as will former Presidents Obama, George W. Bush and Clinton.

Pence also left a note for Harris at the White House, according to a source familiar with the decision, but the details of the note's contents are not known. Pence also spoke to Harris by phone last week to offer assistance ahead of the inauguration.
