Behind the scenes: A top Biden official was unaware of the directive. Administration officials left open the possibility cooperation would resume after a holiday pause. The officials were unsure what prompted Miller's action, or whether President Trump approved.
Why it matters: Miller's move, which stunned officials throughout the Pentagon, was the biggest eruption yet of animus and mistrust toward the Biden team from the top level of the Trump administration.
What happened: Meetings between President Trump's team and the Biden team are going on throughout the government, after a delayed start as the administration dragged its feet on officially recognizing Biden as president-elect.
- Then on Thursday night, Miller — who was appointed Nov. 9, when Trump fired Defense Secretary Mark Esper right after the election — ordered officials throughout the building to cancel scheduled transition meetings.
Pentagon official response: A senior Defense Department official sought to downplay the move, calling it "a simple delay of the last few scheduled meetings until after the new year."
