'Don't Touch My Girlfriend:' Chicago Man ‘Warns’ US President [Video]

U.S. President Barack Obama was "warned" against touching a woman while he was casting his vote on Monday. "Mr. President, don't touch my girlfriend," a Chicago man told Obama, who was standing beside the woman whom the man was referring to.

The incident took place while Obama was standing next to Aia Cooper in a voting booth. Mike Jones, Cooper's fiancé, apparently was in a mood of sarcasm as he asked the U.S. president not to "touch" his girlfriend. Obama was prompt to reply. He said that he "really wasn't planning" to do such a thing. Obama also said that Jones was like a "brother" who would embarrass "for no reason." Cooper later told CNN that she was "embarrassed" after her fiancé had tried to "act smart" with the president.

Cooper told Brooke Baldwin on Tuesday that she was "embarrassed and just shocked." "I was just shaking," she said, "I was like, 'do I have to stand there? I don't really want to stand there.'" Cooper said that she was already nervous before the incident as she had to cast her ballot standing next to the U.S. president. Her fiancé's remark made her situation even worse, she said. The couple, on the other hand, said that they would love to invite the Obamas to their wedding. Cooper said that she would want to meet Michelle. She said that she would hope that the first lady of the United States did not think anything about her.

Cooper earlier apologised on behalf of her boyfriend at the poll. She told Obama that she was not aware that her boyfriend was going to say something like that even though she knew that he would try saying "something smart." The U.S. president apparently took the incident in good humour as he joked about how Cooper would talk about the incident to her family and friends. "I can't believe Mike, he is such a fool," Obama imitated Cooper talking to her family about the incident, "But fortunately, the President was nice about it, so it's alright."

Obama gave Cooper a kiss on her cheek after casting his vote. "Give him something to talk about. Now, he's really jealous," he quipped.
