Biden administration officials are working against the clock doling out billions in grants and taking other steps to try to preserve at least some of the outgoing president’s legacy before President-elect Donald Trump takes office in January.

Donald Trump made a triumphant return to the White House on Wednesday, where outgoing president Joe Biden offered a show of civility to the bitter rival who denied him the same courtesy four years ago.

President Biden and President-elect Donald J. Trump’s brief public display of civility was followed by a two-hour meeting behind closed doors.
