Vice President Harris is in Pennsylvania Sunday afternoon, rallying voters with Election Day less than a week away. Her visit to the Keystone State comes a day after she campaigned with former first lady Michelle Obama in another key swing state — Michigan. Along with Wisconsin, these battlegrounds are key for Harris in November as they make up the "blue wall," or states that voted for former President Trump in 2016, but flipped to President Biden in 2020. After weeks of star-studded rallies, the race remains tight between Harris and former President Trump. In Pennsylvania, the GOP nominee is leading the vice president by a razor thin margin — 48.5 percent to 48.3 percent — according to The Hill/Decision Desk HQ's aggregate of polls. The rally in Philadelphia is scheduled to begin at 4:30 p.m. EDT. Watch the live video above.
