Kamala Harris warms up with Lizzo, Usher as Trump shows off onstage endurance

Kamala Harris and Donald Trump invited star power to the campaign trail this weekend, as they took shots at each other’s endurance and urged early voting in battleground states key to the ever-tightening US presidential race.

At rallies in Detroit and Atlanta Harris brought out pop stars Lizzo and Usher respectively to warm up her crowds, while painting her rival Trump as exhausted and unhinged.

The Republican running for a second go in the White House countered those accusations with a marathon speech in Pennsylvania, as billionaire Elon Musk campaigned for him elsewhere in the state.

Both candidates are fighting on every front to seal up voters’ support in a race that polls suggest is effectively tied with fewer than three weeks to election day.

Harris told voters in Detroit that her opponent’s platform is “self-consuming” while repeating vows to invest in the working and middle classes.

“We stand for the idea that the true measure of the strength of a leader is not based on who you beat down, it’s on who you lift up,” said Harris.
