Trump supporters protest outside Arizona voting center during vote-counting

Supporters of President Trump protested outside an Arizona election center late Wednesday, chanting "count the votes!" as elections officials continued to tabulate ballots in a state that Joe Biden is projected to win.

Why it matters: The Trump campaign was furious that Fox News and AP called Arizona for Biden on Tuesday night with hundreds of thousands of votes still outstanding, as a victory for the Democrat would significantly narrow Trump's possible path to 270 electoral votes.
