PROVIDENCE, R.I. (AP) — A Rhode Island state legislator is calling for tougher penalties for those convicted of sex trafficking a minor.

State Rep. Doreen Costa, a North Kingstown Republican, has introduced legislation that would impose prison sentences of up to 50 years for those convicted of exploiting a minor for purposes of sex trafficking. Currently a conviction carries a prison sentence of up to 40 years.

Costa's bill would also increase criminal penalties for those who attempt to interfere with the enforcement of state sex trafficking laws.

Costa says her bill has the support of more than half of the House of Representatives.

The legislation is scheduled for a hearing on Tuesday in the House Judiciary Committee. No vote on the measure has been set.
