Staffers for Sen. Scott Brown (R-Massachusetts) were caught on video making stereotypical "war whoops" and doing "tomahawk chops" in a confrontation with supporters of Elizabeth Warren, the Democratic candidate for U.S. Senate.

Brown has repeatedly hammered Warren over her claims of Cherokee and Delaware ancestry. But he said he doesn't condone the actions of two of his staffers, who participated in the rally on Saturday.

"It’s certainly something that if I am aware of it, I’ll tell that [staff] member to never do it again," Brown told reporters, The Washington Post reported.

The staffers were identified as Brown's deputy chief of staff Greg Casey and his constituent services counsel Jack Richard. A Republican operative, Brad Garrett, was also seen in the video.
