Biden thanked Fetterman for running as he took the stage and told Fetterman's wife that she was going to be a great senator.

Biden mentioned Fetterman was one of the first officials to respond to the bridge collapse and later referred to him when linking infrastructure investments to middle-class stability.

Fetterman, dressed in a rare suit with his wife Gisele, greeted Biden on the tarmac when he deboarded Air Force One and was pictured observing the bridge construction site before the speech.
