Abortion rights advocates won a rare victory in the Republican-controlled Congress as the Senate voted to allow abortions at U.S. military hospitals overseas. The 51-45 vote yesterday would repeal a new law banning those abortions. But first, the House and Senate must resolve their disagreement on the issue. Last month, a similar move in the House to overturn the abortion ban failed. Kate Michelman, president of the National Abortion and Reproductive Rights Action League called the vote a welcome break from Congress’s unprecedented assaults on women’s reproductive freedom.
