Michigan Gov. Jennifer Granholm (D) said Sunday she's "of course" rooting for the United States in the Olympics.

Granholm, who was born in Vancouver, Canada but moved to the United States at the age of four, said she's backing Americans over Canadians.

"The U.S., come on!" Granholm said jokingly during an appearance on "Fox News Sunday."

"I left Canada when I was four!" she added.

Granholm's declaration comes before a very highly-anticipated matchup between the Canadian and American national hockey teams on Sunday at the Olympics, which are being held in Vancouver.

What's more, Granholm's state shares a number of waterways with Canada, making Michigan a key point of entry for goods coming in from up north.

"I'm American," she emphasized. "I've got dual citizenship."
