HAGERSTOWN, Md. (DC News Now) — President Joe Biden toured the Volvo plant in Washington County on Friday, spending time with workers while he was there and marking National Manufacturing Day.

The plant, which employs about 1,700 people, makes engines, transmissions, and axels for Volvo and Mack trucks.

After landing at Hagerstown Regional Airport around 12:10 p.m., Biden headed to the plant, where he talked about building the economy from the bottom up and middle out.

“America’s reasserting its power,” Biden said as he addressed employees. “We’ve created an average of 350,000 jobs per month.”

The president called out Republicans who call the infrastructure plan “socialist.” Biden said the same people are asking the White House to help build better infrastructure in their districts.

“The middle class built America, and the unions built the middle class,” Biden stated. “I’ve never been more optimistic about America’s progress in my entire life.”

“It makes a difference when we have a pro-worker, pro-union president in the White House,” said Sam Leedy, who has worked at the plant for 24 years. Lee said the visit “recognizes the hard work we do every day.”
