BOSTON (AP) -- Supporters of U.S. Sen. Scott Brown and a staffer from the Massachusetts Republican Party are seen shouting war whoops and performing tomahawk chops in a new video.
The actions are an apparent reference to Democratic challenger Elizabeth Warren's claims of Native American heritage.
The video was posted online by the Democrat-leaning Blue Mass Group. The group said the video was taken at a rally for Brown in Boston on Saturday.
A Brown spokesman confirmed one of those in the video was Republican Party staffer, but declined to say if any Brown staffers were in the video.
Brown told reporters Tuesday he hadn't seen the video, but that it wouldn't be something he'd condone.
Brown stopped short of saying he'd apologize to Native Americans or discipline staffers if they were involved.
