In light of Barack Obama's victory, the Fall Out Boy rocker, 29, has posted a photo of the senator holding him when he was nearly 3 years old. Wentz's mother Dale (right) was one of Biden's legislative assistants at the time.
Wentz, an Obama supporter, said he become so active in politics "because my parents met working for Biden."
"They met on the campaign, so they have this particular affection for Joe," he told the Associated Press on Election Day. "He came to their wedding. If it weren't for Joe Biden, I would not exist as a human being."
