Dozens of Catholic institutions have filed suit against the Obama administration over federal healthcare rules requiring employers to provide contraception coverage to employees. The University of Notre Dame, Catholic University of America and the Archdiocese of New York were among more than 40 groups to file lawsuits on Monday, saying the mandate violates their religious beliefs. The White House relaxed the contraception mandate following a backlash earlier this year, but the lawsuit says the changes do not go far enough. Twenty-eight states already have laws requiring insurers to cover birth control at the same levels of other medications.
