(Reuters) - The U.S. presidential election will be decided in seven states where votes are still being counted that could swing the outcome to either Republican President Donald Trump or his challenger Joe Biden.

Biden held a lead in four of the states that together award 43 Electoral College votes, which could just allow the Democrat to reach the 270 votes he would need to win, while Trump led in three that hold 51 Electoral College votes, which would push his total to 265.
