Former President Donald Trump has defeated Vice President Kamala Harris to return to the White House, CNN projects, in a moment of historic consequence for American democracy.

His projected win in battleground Wisconsin put the Republican over the top with 276 electoral votes as counting continues in some key states.

Trump will return to the nation's highest office four years after losing the 2020 election, attempting to overturn the results, facing two presidential impeachments, a criminal conviction and many other criminal charges.

He's also projected to become only the second president to win two nonconsecutive terms.
