 Iowa's highest court ruled Friday that a ban on most abortions after about six weeks can now be enforced. Planned Parenthood had filed a lawsuit saying the ban violated citizens' rights under the state constitution. By a vote of four to three, the court rejected that argument. Nevada's Secretary of State says a ballot question to enshrine a right to abortion in that state's constitution can appear on November's ballot. Nevada already has a law that makes abortion legal up to 24 weeks, but organizers of the ballot initiative say it's easy for a law to be changed.
