TURTLE CREEK, Pa. —
As the global response to the Trump administration’s sweeping tariffs unfolds, U.S. Sen. Dave McCormick visited Eos Energy Enterprises in East Pittsburgh Monday, highlighting efforts to bolster American manufacturing.
Eos Energy Enterprises, a manufacturer of zinc-powered energy storage, sources 92% of its supply chain from the U.S. and is working to make that 100% by shifting the remaining 8%— currently sourced from Canada, Mexico and Korea — to domestic suppliers.
“The supply chain to support it is 92% from the United States,” McCormick said. “Eight percent is in the process of coming back. It’s a high-performing, lower-cost product that’s going to be critical to meeting growth in energy demand. This is exactly the kind of opportunity we aim for in Pennsylvania.”
Following the factory tour, McCormick addressed reporters’ questions about the impact tariffs have had on the volatile stock market.
Over the past week, market disruptions have triggered inflation concerns and supply chain instability and slowed economic growth.
“The essence of the tariffs, which is to try to bring fairness, makes sense,” McCormick said. “Now they’ve got to be executed in a way that’s ultimately beneficial for Pennsylvania and the country. Let’s give it a little time and see how things play out over the coming weeks.”
McCormick added optimism for a shift, saying, “If we do smart economic things for workers in Pennsylvania, and we achieve fairness, the real economy will be great, and the stock market will follow.”
Eos Energy Enterprises CEO Joe Mastrangelo echoed this sentiment, sharing insights into their commitment to American-made products.
“We started building this supply chain by driving around the Rust Belt in a Ford Taurus, looking for suppliers,” Mastrangelo said. “Now we’re expanding to places like St. Louis and Buffalo to backfill what we’re buying from overseas.”
The Trump administration has defended the tariffs as a way to encourage domestic manufacturing despite market turbulence and global trade retaliation.
“The president’s laid out a path,” McCormick said. “Now I’m looking forward to seeing him negotiate the kinds of deals that’ll ensure fairness.”
