Medford native and TV host Maria Menounos was home on Tuesday to cover Mitt Romney’s election night festivities for “Extra.” She stuck around to film from alma mater Emerson College on Wednesday, and met up with student Quinn Marcus, of mtvU’s “Quinnterviews,” who interviewed Menounos for her own series. Menounos had to tweet to her followers on Tuesday night that she was out at Romney’s party not to support him, but to report on the election. Apparently, some of her fans were disappointed to see that she was in Boston with the former governor. “Guys . . . I’m a journalist — not picking either side. I’m here at Romney headquarters COVERING this for @extratv . . . doesn’t mean I support him,” Menounos tweeted.
