13 GOP lawmakers ask Justice Ginsburg to look at a conflict of interest.

Thirteen Republican members of Congress on Thursday asked Supreme Court Justice Ruth Bader Ginsburg to withdraw from all future cases having to do with abortion because of her affiliation with the NOW Legal Defense and Education Fund.

The House lawmakers said in a letter to the liberal justice that they were concerned about her loaning her name and presence to the Justice Ruth Bader Ginsburg Distinguished Lecture Series, which is co-sponsored by the defense fund, because the fund often files legal briefs in cases before the high court.
