SCRANTON, Penn. – President Obama strolled into the Scranton High School gym today to a rock-star welcome, but one of the guests for his speech apparently couldn’t keep her enthusiasm under control.

As Obama worked the fence line shaking hands with a row of supporters, a woman frantically jumped up and down from behind, then lurched forward to grab Obama by the arm. She clasped his hand first, then grabbed his bicep and aggressively yanked him toward the crowd.

Secret Service agents swarmed to the president’s side, though no direct intervention was needed. Obama eventually loosened her grip and continued on stage, never losing his smile.
