As President Obama voted in Chicago on Monday, a man casually told him not to flirt with his fiancee, who was casting her ballot next to the president. "Mr. President, don't touch my girlfriend," the man said as he walked past.

"I really wasn't planning on it," Obama replied as the embarrassed woman, Aia Cooper, apologized. "Now there's an example of a brother just embarrassing me for no reason. Just for no reason. Now you're going to go home talking to your friends about this."

Obama ended the exchange by giving the woman a kiss on the cheek. "You're gonna kiss me, give him something to talk about," he said. "Now he's really jealous."

Cooper explained the encounter to WLS-TV later that day. "On the cheek, just the cheek-please, Michelle, don't come after me—just the cheek!" she said.
