Biden said that Negri had done the math and said, “You know how many miles you travel on Amtrak, Joey? … 2,200,000 miles… So Joey, I don’t want to hear this about the Air Force anymore.”

Negri retired from Amtrak in 1993, meaning he didn’t work there when Biden was vice president from 2009 to 2017. He died in May 2014.

Biden usually says the story happened in his final year as vice president, but he didn’t include that detail Monday. His mention of his mother’s death suggests it may have happened earlier.
