Pro-life groups are concerned that the president's healthcare law will allow elective abortion as a covered benefit.

The pre-existing condition insurance plan offers coverage to people turned down by private insurers.

Federal officials say elective abortions are barred under the plan, but one state -- New Mexico -- initially listed it as a covered benefit. The state later reversed its stance.

Abortion opponents say the rules governing the program aren't clear and that could lead taxpayer-funded abortions. Federal officials say they're writing guidelines to help clear up the confusion.
