Vice President Kamala Harris and former president Donald Trump both spent the waning hours of their campaigns in the well-trodden swing states of Pennsylvania and Michigan, widely seen as critical to winning the White House, AP reports.

Harris wrapped her day in Philadelphia, where Lady Gaga sang “God Bless America” and Oprah Winfrey appeared on stage with first-time voters. “Our people-powered movement reflects a simple and undeniable truth: that we are all in this together,” Harris said.

Harris didn’t arrive at the vice president’s residence, the Naval Observatory, until 1:41am.

Trump, meanwhile, spent the final hours of the day in Grand Rapids, Michigan, wrapping up around 2am. He took shots at Harris for campaigning alongside celebrities.

“We don’t need a star because we have policy. We have great policy,” he said. Later, he boasted of his own stars: “So many celebrities here, it’s incredible: Mike Pompeo, please stand up,” introducing his former secretary of state.
