TAPPER: And we're back with our 2020 lead. In just a few hours, Joe Biden will formally accept the Democratic nomination for president of the United States. A senior aide for Biden tells CNN there will be significant criticism of President Trump in Biden's speech, but Biden sees the moment as -- quote -- "bigger than Trump" and plans to be forward-looking and optimistic, we're told.
