One anti-abortion group points to a slight increase in abortions at Planned Parenthood clinics in Indiana.
The rallies come in the wake of a controversial video that claims to show Planned Parenthood officials discussing the sale of fetal tissue.
The rallies are in response to videos posted online purportedly showing Planned Parenthood officials discussing the sale of fetal body parts and tissue.
Pro-choice advocates attribute the decline to availability of contraceptives. Pro-life groups cite new laws aimed at restricting or reducing abortions.
Current law requires clinics performing surgical abortions to have a license, but does not mention those that perform medical or chemical abortions.
Indiana saw a 5 percent drop in the number of abortions performed in the state from 2009 to 2010.
