He said the bill would have been able to advance.
He offered an amendment that would allow motorcycle riders age 21 and older to go without helmets if they had at least $1 million worth of health insurance coverage.
Under his latest amendment, younger riders would still have had to wear helmets, and all riders and passengers would have to wear eye protection.

"I don't want to pay for your foolishness of not wearing a helmet," he said.
"If you're willing to step into this and trample on the rights of this minority, whose rights will you trample next?" he asked.
