President Donald Trump is going to a Mack Truck facility in a battleground district in swing state Pennsylvania Tuesday, shifting attention to the U.S. economy in his first major public event beyond the capital since he signed an interim agreement to end the Iran war.

Trump’s trip to the Allentown-area business comes as he works to try to put the conflict — and the higher gasoline prices it caused — in the rearview mirror as November midterm elections draw closer.

It’s the president’s fifth second-term visit to Pennsylvania, a key state whose support in 2016 and 2024 helped him to the White House. The Macungie, Pennsylvania, facility is in the 7th Congressional District, where incumbent Republican Rep. Ryan Mackenzie faces Democratic challenger Bob Brooks in November.

The visit comes amid rising prices that could color the verdict voters render on Trump’s stewardship in the fall. About one-third of U.S. adults approved of Trump’s approach to the economy, according to a June Associated Press-NORC Center for Public Affairs Research poll. That’s in line with last month for Trump on the issue.

The Iran war, which began Feb. 28, has also been a politically difficult issue for the president. Most Americans continued to disapprove of his handling of Iran, according to the June AP-NORC poll, which was being fielded as Trump announced a tentative deal with Iran and concluded just before the interim agreement was signed last week. It found about two-thirds, 65%, of U.S. adults disapprove of how the president is handling issues with Iran, unchanged from May.

Still, while most Democrats and independents view Trump’s actions negatively, only about 3 in 10 of Republicans are unhappy.

Support from districts like the one he’s visiting Tuesday are pivotal to Republicans holding narrow control of the House, where a loss could hobble the president’s final two years in office. Mackenzie, a freshman lawmaker, is looking to hold onto a district Democrats have targeted to flip. Brooks, president of the state firefighters’ union, has support from Democratic Gov. Josh Shapiro, who’s also seeking reelection this year.

Trump’s predecessor, Democrat Joe Biden, also visited the Mack Truck facility to highlight regulations aimed at promoting manufacturing jobs. Manufacturing employment peaked in 1979 at nearly 19.6 million jobs. It trended downward after the 2001 recession and the 2007-09 Great Recession. The figure now stands at 12.6 million as of May, according to the Bureau of Labor Statistics.

The visits underscore Pennsylvania’s status as a crucial swing state.

Trump visited Mount Pocono in December to road test messages that he’s addressing affordability; in July 2025, he was in Pittsburgh to tout tens of billions of dollars of recent energy and technology investments in the state; in June 2025, he was in West Mifflin to tell steelworkers he was doubling the tariff on steel imports to protect the industry; and in March 2025 he attended the NCAA wrestling championship in Philadelphia.
