Biden declared president-elect as challenges loom

The incoming president, however, is likely to experience a potentially turbulent transfer of power, as Trump's campaign has indicated that it will challenge election outcome in a handful of states with lawsuits.

Trump immediately accused Biden of "rushing to falsely pose as the winner" as the media outlets made their calls for his rival.

"This election is far from over," he said in a statement.

"Joe Biden has not been certified as the winner of any states, let alone any of the highly contested states headed for mandatory recounts, or states where our campaign has valid and legitimate legal challenges that could determine the ultimate victor," Trump said in the statement.

William C. Banks, distinguished professor emeritus at Syracuse University College of Law in New York, said it is highly unlikely that Trump can do anything to change the race outcome.
