Sources told ABC News that Trump has requested a large sendoff hours before President-elect Biden takes the oath of office Wednesday.

Sources say Trump plans to depart the White House next Wednesday morning, choppering via Marine One to Joint Base Andrews where he is expected to give remarks to supporters and departing members of his administration.

Sources add that Trump has requested the event to have a "military-like feel" though details are still not finalized. The president will then fly down to his Mar-a-Lago club in Florida onboard Air Force One with a small number of staffers who will be part of his post-presidency operation, according to the sources.

During a news conference Friday, D.C. Mayor Muriel Bowser said the National Mall is temporarily closed to the public through at least Thursday.

Thirteen metro stations inside the security perimeter will also be closed.

Bowser said the National Mall closure came at the request of and in cooperation with the Secret Service and the National Park Service.

The mayor urged Americans to enjoy the inauguration virtually from home this year.

She also discussed the city’s beefed-up security ahead of the inauguration but told D.C. residents she doesn’t expect the security measures currently in place to last too long after Biden takes office.

The nomination hearing for Biden’s pick for director of national intelligence, Avril Haines, has been postponed. It was originally scheduled for Friday.

A joint statement from Senate Intelligence Committee Acting Chairman Marco Rubio and Vice Chairman Mark Warner on Thursday confirmed the postponement. It did not give specific reasons, but referenced the “unusual circumstances on Capitol Hill.”

Rubio and Warner added that they "look forward to holding a hearing next week" for Haines, but did not list a specific date.

Senate Majority Leader Mitch McConnell has indicated that the Senate impeachment trial should take place after Trump leaves office.

The Senate impeachment process will begin "at our first regular meeting following receipt of the article from the House," McConnell wrote in a new statement, saying he believes it would be best for the country to have an orderly transfer of power completed before a trial begins.

The Senate is currently scheduled to return to Washington on Tuesday, making that the earliest day for any Senate action related to the trial to occur -- but McConnell's message to House Speaker Nancy Pelosi and Democrats is for them not to send the articles until after Biden is sworn in.

McConnell has no control over when a trial begins -- that is determined by the articles sent to the Senate​​.

While House Speaker Nancy Pelosi has so far declined to say publicly when the House will send the article over to the Senate, a source involved in the Democratic leadership deliberations told ABC News earlier Wednesday Pelosi planned to send the article to the Senate next week.

"Even if the Senate process were to begin this week and move promptly, no final verdict would be reached until after President Trump had left office. This is not a decision I am making; it is a fact. The President-elect himself stated last week that his inauguration on January 20 is the ‘quickest’ path for any change in the occupant of the presidency," McConnell wrote.

"In light of this reality, I believe it will best serve our nation if Congress and the executive branch spend the next seven days completely focused on facilitating a safe inauguration and an orderly transfer of power to the incoming Biden Administration."

McConnell confirmed on the record earlier Wednesday that he is considering voting to convict Trump on inciting an insurrection.
