President Barack Obama has urged Democrats of all ethnic backgrounds to get out and vote for Hillary Clinton, warning that the fate of the US republic - and the world - is at stake.
He said her Republican opponent Donald Trump was a threat to hard-earned civil rights. President Obama was speaking at a rally in North Carolina.
Mr Trump said Mr Obama should stop campaigning for Mrs Clinton and focus on running the country. He said Mrs Clinton had become "unhinged" in recent days.
Meanwhile, the FBI is now investigating new emails that may be linked to its probe into Mrs Clinton's private email server.
The agency's director, James Comey, has faced a fierce backlash for announcing the move just 11 days before the presidential election.
Earlier, Mr Obama implicitly criticised him over the new inquiry into Mrs Clinton's email use.
