Democratic Party presidential candidate Kamala Harris is due to visit three battleground states on Monday – Wisconsin, Michigan and Pennsylvania
The vice-president’s Republican opponent, former President Donald Trump, is heading for North Carolina – which was badly hit by Hurricane Helene in September
Trump says presidential candidates should have to take a cognitive test in a swipe at Harris during an event in Pennsylvania, a swing state where he earlier made a campaign stop at a McDonald’s
Harris says Trump’s frequent personal attacks “demeans the office” of president and accuses him of being “unstable”
