Sen. Scott Brown, R-Mass., has criticized Democratic opponent Elizabeth Warren for claiming Native American ethnicity, and the Washington D.C. Board of Elections and Ethics does not approve of those criticisms.

DCBOEE tweeted a Talking Points Memo blog post called “Really, Scott Brown?” that denounces one of Brown’s remarks about the issue as “ignorant and offensive.”

The tweet was sent about three hours ago, according to Twitter, but it was deleted moments ago.
