2024 election live updates: Crowd gathers for Trump's Madison Square Garden rally

After a three-hour podcast interview with Joe Rogan, Trump is expected to start his rally in Traverse City, Michigan, at 10 p.m. ET -- three hours after he was scheduled to take the stage.

As several hundred supporters dispersed from the airport hangar, Trump appeared on the Jumbotron notifying the crowd of his tardiness.

"Traverse City, I'm not going to be there for a little while. Filming Joe Rogan," Trump said.

He continued, "It's a Friday night, so we can sit around and do an extra special job when we get there. ... It's all about winning, and we had to spend some extra time with some people, and lots of people, actually, but we are going to do a special performance, and we'll be there, and I think you'll see the plane land, and the whole thing."

Trump concluded his message by thanking his supporters for sticking around.

Many attendees did call it quits on the former president and headed home early.

Minnesota Gov. Tim Walz ended his swing through eastern Pennsylvania on Friday with an energetic rally in President Joe Biden's hometown of Scranton.

The governor topped off his remarks by saying that Biden has "secured his place in history" by upholding a presidential tradition of putting the country above himself.

Speaking of the city of Scranton, Walz said, "This is a place with a long tradition of people who know something about hard work and people know what it means to serve this nation. ... I want you to know that the country owes a huge debt to you and a huge debt to Joe Biden," Walz said.

Chants of "Thank You, Joe" erupted from the crowd.

With Vice President Kamala Harris in Texas on Friday night for a rally centered on abortion rights, Walz also talked directly about reproductive policies in the state.

"Would this surprise you that in the most recent data, maternal mortality rates in Texas have shot through the roof?" he said. "So let's just be very clear. Women are dying because of these decisions they made, and it's absolutely immoral."

Country legend Willie Nelson took the stage at Harris' rally in Houston.

He played "Mammas Don't Let Your Babies Grow Up to Be Cowboys" and "On the Road Again."

Beyoncé is also expected to appear at the rally tonight in her hometown.

Republican vice presidential nominee Sen. JD Vance, speaking during a town hall with North Carolina voters on Friday, said U.S. adversaries don't fear Vice President Kamala Harris.

"Why do you have Russia invading Ukraine during Kamala Harris' watch and why do you have Iran and Hamas attacking Israel during Kamala Harris' watch?" Vance said at the town hall in Monroe, North Carolina, moderated by Republican National Committee Co-Chair Laura Trump. "And why do you have China saber rattling during Kamala Harris' watch? It's because who could possibly fear Kamala Harris? No one, right?"

Vance added, "This is a woman who is terrified of softball media interviews and we think that she's going to sit in a room with Vladimir Putin and Xi Jinping."

Vance said that when former President Donald Trump was in office, U.S. adversaries feared the former president.

"That fear kept a lot of aggression in check, and it kept a lot of wars that otherwise would have started from starting in the first place," Vance said.
