Watch Harris' call with Biden: "We did it, Joe"

There are no plans for President Trump to invite president-elect Joe Biden to the White House in the coming days, according to a source familiar with the matter. Traditionally, there is an Oval Office meeting between incoming and outgoing presidents.

Trump has often referenced his Nov. 10, 2016, meeting with Obama, including what he was told about North Korea.

Trump, as made clear in his statement, is still contesting the election, so those traditional steps of a transition won't happen anytime soon.

Less clear is whether the other, more granular aspects of the transition will occur, particularly at agencies and among staff. One person familiar with the matter said there haven't been explicit instructions disseminated from the White House on how to proceed.
