Cribbed from one of the reproductive rights organizations:

The Bush administration is proposing a new regulation that could discourage doctors and health-care clinics from providing birth control to women who need it.

This proposed regulation deliberately confuses the definitions of contraception and abortion and could seriously jeopardize state laws and policies that protect women's access to birth control. For example, state laws that require hospitals to provide sexual-assault survivors with access to emergency contraception could be jeopardized.
