As part of his re-election campaign, Sen Scott Brown (R-MA) has attacked his opponent for mischaracterizing herself as Native American. Elizabeth Warren does have Cherokee ancestry, but Brown claims she abused that to gain a professional advantage by listing herself as a minority.

Perhaps Brown’s sensitivity to the issue ends there. On Tuesday, a video surfaced of Brown staffers doing a ‘tomahawk chop’ and making ‘war whoop’ sounds at Warren supporters, an apparent allusion to the dust up over Warren’s heritage. The incident occurred outside of a pub in Boston on Friday.
