United States presidential candidate Donald Trump is warning a cloud of investigation would follow his Democratic rival, Hillary Clinton, into the White House if she were elected.
His remarks, evoking memories of the bitter impeachment battle of the 1990s over Bill Clinton, are a closing campaign argument aimed at pulling in any doubting Republican voters.
Meanwhile, Ms Clinton and her allies, led by President Barack Obama, have told voters to get serious about what they say are the dangers of Donald Trump.
Polls show Mr Trump closing in on Ms Clinton in some of the states most in question, with her campaign rushing to shore up support in long-standing Democratic strongholds.
