5 Things to Know About Chelsea Clinton's Fiancé Marc Mezvinsky

As the final countdown to the wedding this weekend begins, let us welcome to the Clinton family, Marc Mezvinsky!

But who is this guy marrying former first daughter Chelsea Clinton, 30 – and can he keep up with the Clintons? Here are five things to know about the businessman.

He works on Wall Street
The Stanford alum – like Chelsea – means business: he currently works at the hedge fund G3 Capital. Before that, he was an investment banker at Goldman Sachs. This meshes well with Clinton’s former job at Avenue Capital Group.

Politics is in his blood, too
He’s the son of former U.S. congressman Edward Mezvinsky and former U.S. congresswoman Marjorie Margolies-Mezvinsky, who also once ran for Lieutenant Governor of Pennsylvania. Interestingly, Congresswoman Mezvinsky was the deciding vote in passing President Clinton’s then-controversial Omnibus Budget Reconciliation Act.

His dad went to prison
Despite his public service, in 2001 Mezvinsky’s dad pleaded guilty to 31 counts of fraud, involving almost $10 million. He was released from federal prison in 2008.

He’s Jewish
Clinton’s fiancé, who is Jewish, will invite another religious perspective into the family. (Hillary Clinton is Methodist, while the former President is Southern Baptist.) No word yet if Chelsea’s converting, but she did attend Yom Kippur services with Marc in 2009 at New York’s Jewish Theological Seminary, according to the Associated Press.

He hit it off with Bill
The father of the bride’s opinion always matters – especially when your future in-law is Bill Clinton. And Bill seems to be as head-over-heels as Chelsea: “He is great,” the former president said in December, as he left a panel discussion at Columbia University. “He is a great human being.”
