Harris will spend her final day on the campaign trail holding rallies across Pennsylvania, a battleground, must-win state that both Republican and Democratic strategists see as key to winning the Oval Office.

Harris will start the day in Joe Biden's hometown of Scranton before holding a rally in Allentown and then making a local stop in Reading. On Monday evening, Harris will hold rallies in Pittsburgh and Philadelphia. The latter two will feature musical guests, according to the campaign, including Lady Gaga in Pittsburgh and Katy Perry in Philadelphia.

Pennsylvania went for Trump in the 2016 presidential election but switched to Biden in 2020. Polls show Harris and Trump tied in the state.

Trump will split his time between three battleground states on the final day before the election.

Rallies are planned in Raleigh, North Carolina; Reading, Pa.; Pittsburgh and Grand Rapids, Michigan, according to the Trump campaign.

Grand Rapids occupies a unique position in the history of the Trump campaign: Michigan's second-largest city was Trump's final stop on election night in his two previous presidential campaigns.
