Sen. Chuck Grassley (R-Iowa) said today he still has questions about the constitutionality of an individual health insurance mandate.
"Whether it's constitutional or not ought to have the most debate," he said in a conference call with reporters.
"I'm afraid the way this thing is going that there's not enough questions raised about the individual mandate, that maybe there aren't enough people concerned about it," he added.
Critics of the mandate say the constitution grants no authority to demand individuals buy insurance.
Supporters have argued that the insurance market is a matter of interstate commerce, giving Congress all the authority it'd need for the mandate.
