Decision Desk HQ is one of the many news sites that follow the elections with their own analysts and call state results. They are the first to state that they think Joe Biden is the president.
Decision Desk HQ projects that @JoeBiden has won Pennsylvania and its 20 electoral college votes for a total of 273.
Joe Biden has been elected the 46th President of the United States of America.

While I am repeating their claim, it should be treated with great caution because the AP, the one that I most rely on, has made no such call, and neither have Fox News, NBC, CBS, ABC, CNN, the New York Times, or the Washington Post.
