President Joe Biden traveled to Philadelphia on Labor Day to tout his pro-union stance and his various efforts to improve America’s middle class and the economy during the annual Tri-State Labor Day Parade.

“America’s support for union is higher today than any time in nearly 60 years,” Biden said at the parade, which was hosted by the AFL-CIO. “I’ve continued to call on Congress to fully and finally pass to Protect the Right to Organize, the PRO Act … too many companies are still playing unfair, trying to prevent organization.”
