Republicans have made headlines this year by demanding that people collecting unemployment benefits and public assistance be subject to drug testing. Now Iowa Republican state senator Mark Chelgren (Ottumwa) proposed Thursday that people who receive child support payments should also be drug tested if the person paying the support requests it, according to a report at Think Progress.

Chelgren submitted the measure as an amendment to a budget bill currently before the Iowa state senate. He claims the idea for the proposal came from an unidentified constituent who was concerned that his ex wife was using child support money to buy drugs.

Under the provision, payers of child support would be able to have their former partners tested for drugs every six months if they were willing to cover the costs associated with testing.
