Justice Samuel Alito wrote the majority opinion in the ObamaCare case, finding the contraceptive mandate in its current form "unlawful." The court's four liberal justices dissented.
White House Press Secretary Josh Earnest said Monday afternoon that the decision "jeopardizes the health of women who are employed by these companies," but said the administration would respect the ruling.

Earnest did not get into specifics, saying they are still assessing the decision and trying to determine which companies are affected.
