Indiana legislators are trying to make it harder for clinics to prescribe abortion-inducing drugs.

In a 33-16 vote, the state Senate passed a bill Tuesday requiring women seeking the RU-486 pill to have an ultrasound first.

The measure also requires drug-dispensing clinics to conform to the same regulations as surgical clinics.

The bill now goes to the statehouse, where Republican leaders expect it to pass.

If it passes, Indiana will become the ninth state to require ultrasounds before abortions.
