The rally, which was being held in Independence Mall in Philadelphia on Monday, was also attended by Hillary’s husband, former President Bill Clinton and First Lady Michelle Obama.
The attendance set a new record for Clinton after another rally in Ohio drew 18,500 people, a campaign aide told reporters traveling with the former secretary of state.
During his speech, Obama urged US voters to “reject fear and choose hope” on Election Day.

"I'm betting that the wisdom and decency and generosity of the American people will once again win the day and that is a bet that I have never, ever lost," he added.
Clinton, her Republican rival Donald Trump and their surrogates spent Monday crisscrossing the key battleground states to gain support on the eve of Election Day.

Following Obama’s speech, the former first lady addressed the event, saying that "there is a clear choice in this election, a choice between division or unity."
"Between an economy that works for everyone or only those at the top, between strong, steady leadership or a loose cannon who could put everything at risk," she added.
‘Hillary Is Face of Failure’
Trump, meanwhile, presented himself as the face of change in the US and slammed Clinton’s political record as secretary of state.

"Hillary is the face of failure. She's the face of failure," the billionaire businessman said at a rally in Scranton, Pennsylvania.
"They say we're tied in Pennsylvania. I don't think so. I think we're going to blow them out tomorrow. Blow them out," Trump added.
