Childhood pals, fellow Stanford alums and future husband and wife, Marc Mezvinsky and Chelsea (here, attending a football game on Hilton Head, South Carolina, in 1996) have plenty in common – including family politics. His parents, former Rep. Ed Mezvinsky (D-Iowa) and former Rep. Marjorie Margolies-Mezvinsky (D-Pennsylvania), are longtime pals of the Clintons. "They had that connection," a friend of the couple told PEOPLE in 2009. "When not-such-great things were happening in [Chelsea's] life, he was the protector."
