Christie On Obama Photo Ops: 'Do You Want Me To Wear My Romney Sweatshirt?' (CNN) -- New Jersey Gov. Chris Christie on Friday continued to defend his appearance with President Barack Obama last year when the president came to survey the damage from Superstorm Sandy, just days before the presidential election. Critics decried the Republican governor for standing side-by-side with Obama, arguing Christie, who served as a top surrogate for GOP nominee Mitt Romney, helped bolster the president's image shortly before voters took to the polls. But Christie stands by his decision. "I said to some of my Republican friends in the aftermath of this, like well what did you expect me to do when the president showed up? Do you want me to wear my Romney sweatshirt when I was standing with him? What exactly did you expect me to do?" Christie said while keynoting a Washington conference on volunteering and service.
