WASHINGTON - President Donald Trump's bid to discredit the integrity of the U.S. election results and use legal action to block the completion of vote tallies in some states has raised fears, even among his own aides, that he will refuse to concede and seek to undermine a potential transfer of power after Joe Biden's victory Saturday.

WASHINGTON - President Donald Trump refused Wednesday to commit to a peaceful transfer of power if he loses the election, asserting that if he doesn't win, it will be because of fraudulent mail-in voting and not because more Americans voted against him.
