Jay Z will hold a concert for Hillary Clinton in Cleveland just days before Election Day.

The Democratic presidential candidate's campaign says the hip-hop artist will perform on Nov. 4. He'll also be joined onstage by special guests.

Jay Z campaigned for President Barack Obama in 2008 and 2012.

Jennifer Lopez, Jon Bon Jovi and Katy Perry are also among the stars staging shows for Clinton in the next two weeks.

Lopez will appear in Miami on Saturday to encourage Florida voters to back Clinton. Bon Jovi will headline concerts in Pittsburgh on Thursday and in Tampa, Florida, on Nov. 5. And Perry will perform in Philadelphia on Nov. 5.

Even as his path to the presidency narrows, a defiant Donald Trump is insisting he is "winning" and urging his supporters to defy what he is calling an establishment conspiracy to deny the White House to his populist movement.

Trump, in the middle of a three-day swing through battleground Florida as thousands began voting there in person, hammered the "disgusting" media on Monday for its "phony polls" that he claimed were the latest signs of a "rigged election."

"The media isn't just against me. They're against all of you," Trump told cheering supporters in St. Augustine. "They're against what we represent."

"I believe we're actually winning," he said.

But even as Trump publicly displayed his trademark bravado, his team conceded publicly as well as privately that he was trailing — and that crucial Pennsylvania may be slipping away to Democrat Hillary Clinton. That would leave him only a razor-thin pathway to the 270 electoral votes needed to win the White House on Nov. 8.
