President Obama found himself in an unusual situation Monday.

As he was casting his ballot early in Chicago, minding his own business behind the voting booth, a young man walked by and warned him "don't touch my girlfriend."

The girlfriend, Aia Cooper, who was voting in the booth next to Obama, was humiliated, to say the least. "I really wasn't planning on it," Obama joked with the woman. "There's an example of a brother just embarrassing you, just for no reason whatsoever."

"And now you'll be going back home and talking to you friends; what's his name?" the president asked.

"Mike," Cooper said.

"'I can't believe Mike. He's such a fool,'" Obama said, impersonating the woman.

"He really is," she agreed.

Obama continued: "'I was just mortified. But, fortunately, the president was nice about it. So it's all right.'"

"I am freaking out right now," she said, laughing.

The president got the last laugh, though.

"Give me a kiss and give him something to talk about," the president said, as he gave Cooper a hug and a peck on the cheek. "Now he's really jealous."

But Cooper downplayed the moment.

"He gave me a hug and a kiss on the cheek. Just the cheek," she told ABC's Chicago station WLS. "Please, Michelle, don't come after me!"
