Trump was impeached by the House for a second time last week.
President Donald Trump is slated to hand over control of the White House to President-elect Joe Biden in three days.
The House of Representatives voted to impeach Trump last Wednesday on an article for "incitement of insurrection" for his role in the Jan. 6 attack on the U.S. Capitol -- making him the only president to be impeached twice.

Biden on Thursday announced his slate for new leadership at the Democratic National Committee, including former South Carolina U.S. Senate candidate Jaime Harrison to be the next chair of the DNC.
Harrison, who lost the 2020 race to GOP Sen. Lindsey Graham last year, despite breaking numerous fundraising records, will officially become DNC chair after the full committee votes on Jan. 21, the day after Biden's inauguration.
Graham congratulated Harrison on the news in a tweet earlier Thursday.
In addition to Harrison, Biden also announced the names of four DNC vice chairs, all of whom were prominent backers of his presidential campaign, including Michigan Gov. Gretchen Whitmer, who served as a campaign co-chair.
Whitmer is joined by Atlanta Mayor Keisha Lance Bottoms, Illinois Sen. Tammy Duckworth and Texas Rep. Filemon Vela as new DNC vice chairs.
House Speaker Nancy Pelosi called Harrison an "inspiring, energizing and influential" in a press release.
"As former Chair of the South Carolina Democratic Party and senatorial candidate, Jaime brings an outstanding track record of success -- from galvanizing the grassroots, mobilizing millions and shattering fundraising records -- that will be critical during this pivotal moment for our Party and Country," she added.

During an unscheduled stop on Capitol Hill, Vice President Mike Pence greeted National Guardsmen and telling them that he had just come from a briefing where he heard about their efforts.
He thanked the personnel for "stepping forward for your country" to make the historic transfer of power possible.
"It's been my great honor to serve as your vice president and I want to thank you for your service," Pence said.
The vice president then spoke to individual guardsmen asking them where they are from and how long they served.
About 20,000 National Guard members are expected in Washington this week to protect the city ahead of Biden's inauguration.
"Have a safe inauguration," Pence said.

Congressional Democratic leaders commended Biden's announcement outlining his COVID-19 emergency relief proposal.
"The emergency relief framework announced by the incoming Biden-Harris Administration tonight is the right approach. It shows that Democrats will finally have a partner at the White House that understands the need to take swift action to address the needs of struggling communities," House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer said in a statement.
"We will get right to work to turn President-elect Biden's vision into legislation that will pass both chambers and be signed into law," they added.
"The robust package announced by President-elect Biden and Vice President-elect Harris shows we now have the necessary leadership in the Executive Branch to turn this around and we are ready to get to work to deliver aid without delay," Pelosi and Schumer said.
