From Katie Glueck in Wilmington, Delaware for the New York Times:
(7:00 p.m.) Biden had planned to address the nation tonight, but there are indications he may well not do so until the race is called. Things are fluid here in Wilmington!
(7:57 p.m.) People familiar with the Biden campaign’s thinking say he may speak tonight even if the race isn’t called, but the tone will be shaped by the results that are in. Things are still fluid.
