Democratic presidential candidate Kamala Harris and her Republican rival, Donald Trump, delivered radically different messages on the U.S. campaign trail on Monday as they sought to win over undecided voters in the two weeks before Election Day.

Vice President Harris, campaigning alongside former Republican lawmaker Liz Cheney in the three midwestern battleground states, argued that Trump, the former president, was a threat to democracy.

As the election draws closer, Harris has been sharpening her attacks on Trump's fitness for office, often calling him "unstable" or "unhinged" and questioning his temperament.
