Caswell came under fire from Michigan Public Radio for a 2011 proposal to issue the Michigan state $80 clothing allowance for children that receive state welfare assistance as an $80 gift card redeemable at secondhand clothing stores, such as Goodwill and Salvation Army, rather than just adding another $80 credit to the Bridge Card account that would be untraceable in how it was actually spent. The Michigan Radio article and a subsequent article in the Michigan Messenger incorrectly stated that this proposal would affect the clothing allowance for foster children; however, the foster care clothing allowance is a different program and was never a part of Caswell's proposal. Under the current system, DHS issues each year, on average, an additional $80 to a child's parents' Bridge Card for the clothing allowance. However, once deposited on the card, the state has no way to ensure that parents actually spend the clothing allowance money on clothing for their child. In making the proposal, Caswell said, "I never had anything new...I got all the hand-me-downs. And my dad, he did a lot of shopping at the Salvation Army, and his comment was — and quite frankly it's true — once you're out of the store and you walk down the street, nobody knows where you bought your clothes." After contact from a constituent, he revised the plan to also include major retailers, but the gift cards will remain only redeemable for clothes and shoes. “My sole goal in this proposal is to make sure that children receive the clothing allowance that the state has provided for them and not have it used for anything else,” said Caswell. “I believe this solution will go a long way to achieving that objective. If anyone else has a better idea on how we can ensure the money goes for clothing alone, I very much welcome those suggestions and urge you to share your ideas with me. I appreciate the input I have already received that has resulted in making the proposal better.”
