Republican Donald Trump returned to western Pennsylvania on Saturday, telling supporters in the final weeks of the presidential campaign that his trade and immigration policies would usher in a “new golden age” in America.

During his appearance in Latrobe, the former president accused Vice President Kamala Harris, the Democratic nominee, of enabling what he called an “invasion” of undocumented immigrants across the U.S.-Mexico border. As he has in the past, Trump questioned Harris' intelligence and said she was more liberal than prominent progressives like U.S. Sen. Bernie Sanders (Ind., Vt.), whom he called “Crazy Bernie.”

“So you need to tell Kamala Harris that you’ve had enough and you just can’t take it anymore. We can't stand you. “You’re the worst as — vice president,” Trump said. “…Kamala, you’re fired. Get out of here.”

In his speech at Arnold Palmer Regional Airport, Trump praised the venue's namesake, the late golf legend and Latrobe native. “This is a guy who was all man,” Trump said of Palmer, calling him “strong and tough.”

“When he was showering with the other pros, they came out there and said, 'Oh my God, this is unbelievable,'” Trump said. The Harris campaign posted a clip of those remarks on X, calling the episode a “long, confused ramble.”

The campaign was referring to her comments about Trump last Saturday in Detroit. “He’s becoming more and more unstable and unstable,” she said. “The American people are seeing it, witnessing it in real time.”

Latrobe is a predominantly white, working-class community of 8,000 residents in rural Westmoreland County, about 40 miles east of Pittsburgh. Trump held 63% of the vote in Westmoreland County in 2020, when he lost Pennsylvania and the Electoral College to then-candidate Joe Biden.

Both campaigns view Pennsylvania as a critical battleground state, and Harris is expected to return Monday. Her campaign said she would run in Chester County with former U.S. Rep. Liz Cheney, the Wyoming Republican who supported the Democratic vice president. The Trump campaign announced it would host a “Black Men's Barbershop Talk” roundtable event with U.S. Rep. Byron Donalds (R., Fla.) on Sunday in Philadelphia.

In his bid to retake the White House, Trump is once again banking on voters in rural and post-industrial areas like Westmoreland, where coal mining was once a major industry. Supporters who stood behind Trump at Saturday's rally held signs that read “Save Our Fracking” and “Save Our Steel.”

About an hour after Trump's speech, several steel workers joined him on stage to take a photo and presented him with a hard hat with his name on it. The United Steelworkers union has endorsed Harris — and reiterated his support with a post on X-Saturday – but Trump says he has the support of the base.

He repeated his criticism of an influx of Haitian migrants to the small western Pennsylvania town of Charleroi who are in the country legally as part of a humanitarian program. Trump stuck to his false claim that the 2020 election was stolen and reiterated his baseless claim that Harris didn't actually work at McDonald's. The vice president has cited this career path as part of her civic upbringing. Trump is expected to visit the Philadelphia area on Sunday to “work the fryer” at McDonald's, The Inquirer reported.

Trump took on a familiar group of perceived political opponents: generals who have criticized him, like Mark Milley, the former chairman of the Joint Chiefs of Staff, who reportedly called Trump a “fascist” (“what a bunch of lightweights,” said Trump). ; Federal prosecutors (“Department of Injustice”); and Fani Willis, the Atlanta-area district attorney whose election interference case against Trump has stalled (“They had Fani – FANI…that was a fraud”).

Saturday's western Pennsylvania rally came days after Trump campaigned in Montgomery County, where his town hall-style event took an unusual musical turn after two of his supporters suffered medical emergencies. Trump stood on stage for about 30 minutes as music played and he moved to his playlist.

The Harris campaign said he acted “confused.”

Local Republicans claimed Trump and the crowd was just having fun.
