On a day when Senator Scott Brown sought to fan further questions about Elizabeth Warren’s professed Native American heritage, Boston Mayor Thomas M. Menino, who has not been shy about praising Brown, made clear he is fed up with the issue.

“I think she has come clean but nobody has let her off the hook,” Menino said. “It’s not relevant at all in the campaign. Let’s talk about the real issues: education, housing, crime. Those are the real issues we should be talking about. This is one of the issues that you [use to] try to divert as a candidate because you can’t deal with the real issues.”
