BOSTON (AP) - Republican U.S. Sen. Scott Brown has launched a new television ad highlighting his Democratic challenger Elizabeth Warren's claims of Native American heritage.
The 30-second ad features clips of news reports on Warren's claims.
Warren has said she was told as a child that her mother was part Cherokee and part Delaware Indian and that she never questioned that story.
The Harvard Law School professor listed herself in law school directories as having Native American heritage, but said she gained no professional advantage.
Charles Fried, a member of the committee that reviewed Warren for the law school job, has said the subject of her ancestry was never mentioned.
Brown has called on Warren to release personnel records.
Warren said Brown is focusing on her heritage to distract from his Senate record.
