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

Donald Trump is finally getting his Madison Square Garden moment.

With just over a week to go before Election Day, the former president will take the stage Sunday at one of the country's most iconic venues, hosting a hometown rally to deliver his campaign's closing message against Democratic Vice President Kamala Harris.

"Madison Square Garden is the center of the universe," said Trump campaign senior adviser Jason Miller, noting the venue's storied history hosting events including the 1971 "Fight of the Century."

Outside the arena, the sidewalks were overflowing with Trump supporters in red "Make America Great Again" hats. There was a heavy security presence. Streets were blocked off and access to Penn Station was restricted.

The rally is one of a series of detours Trump has made from battleground states, including a recent rally in Coachella, California - best known for the famous music festival named after the town - and one in May on the Jersey Shore. This summer he campaigned in the South Bronx.

Harris vice presidential nominee Minnesota Gov. Tim Walz likened Trump's rally later today at Madison Square Garden to the Nazi rally held there in the 1930s ahead of World War II.

Speaking at a reproductive freedom bus tour kickoff near Las Vegas, Walz warned the crowd that Trump and his campaign are aware of the parallel.

"Donald Trump has descended into madness over the last few weeks, and I think some of you don't miss on this -- Go do your Google on this," he said.

"Donald Trump's got this big rally going at Madison Square Garden. There's a direct parallel to a big rally that happened in the mid 1930s at Madison Square Garden and don't think that he doesn't know for one second exactly what they're doing there," he said.

In February 1939, The German American Bund -- a pro-Nazi organization for Americans of German descent -- held a rally at MSG with about 20,000 attendees.

Walz's statement comes after other high-profile Democrats have suggested this similarity, including 2016 Democratic presidential nominee Hillary Clinton.

"One other thing that you'll see next week... is Trump actually re-enacting the Madison Square Garden rally in 1939. I write about this in my book," Clinton told CNN on Thursday.

Speaking at a Philadelphia church Sunday morning, Harris sought, without naming her opponent, to describe the contrast voters face.

"What kind of country do we want to live in?" she asked congregants. "What kind of country do we want for our children and our grandchildren -- a country of chaos, faith, fear and hate, or a country of freedom, justice and compassion?"

Harris cited Scripture to discuss the "heavy" work required over the next nine days, and the "joy" that will follow.

"These next nine days will test us. They will demand everything we've got. But when I think about the days ahead and the God we serve, I am confident that his power will work through us because church, I know we were born for a time such as this, and I have faith he is going to carry us forward.

"And the road ahead won't be easy. It will require perseverance and hard work. But in times of uncertainty, Scripture reminds us, weeping may endure for a night, but joy cometh in the morning. The path may seem hard, the work may seem heavy, but joy cometh in the morning, and church morning is on its way," she said.

The vice president delivered a unifying message, saying, "This moment in our nation has to be about so much more than partisan politics. It must be about the good work we can do together, about our fundamental values and about who we are as Americans and as people of faith here in Pennsylvania right now, each of us has an opportunity to make a difference."

"In just nine days, we have the power to decide the fate of our nation for generations to come. And on this day, then on this beautiful Sunday morning, I am reminded that God expects us to help him. We got work to do," Harris said.

Trump's vice presidential nominee Sen. JD Vance was pressed on Sunday on Trump calling his domestic political opponents "the enemy from within."

In a recent Fox News interview, Trump referred to California Rep. Adam Schiff and former House Speaker Nancy Pelosi as "an enemy from within." Asked on NBC's "Meet the Press" if he believes Schiff and Pelosi are more dangerous than Russia and China, Vance tried to clarify what Trump said, telling Kristen Welker, "Those folks pose a greater threat to United States's peace and security.

"America is strong enough to stand up to any foreign adversary," Vance said.

Pressed if he agrees with Trump's comments, Vance said "that the biggest threat we have in our country, it's not a foreign adversary."

On CNN's "State of the Union," Vance insisted that Trump's "enemy from within" comments were not directed at political opponents.

CNN's Jake Tapper quoted Trump's previous statements to Vance, saying, "I'm talking about what he said publicly, he wants to use the military to go after the enemy within, which is the American people," Tapper said.

Vance fired back with, "He did not say that, Jake. He said 'far-left lunatics.' He's talking about people rioting after the election."

"He said about using the military that far-left lunatics, people who riot in the wake of an election, people who burned down American cities in the summer of 2020," Vance said. "Yes, we should have a federal law enforcement response."
