“I think the concept is right,” Ryan, the chairman of the House Budget Committee, said at a town hall meeting earlier this week, according to the Wisconsin Reporter news site.

In an emailed statement to The Hill, Ryan clarified that he does not support the Senate’s legislation on the issue.

“It’s got to be done the right way. I think the legitimate concern is can it be used to do other forms of taxation or retroactive taxation? You have got to make sure it doesn’t do that. I don’t think the Senate bill is written in a tight enough way to do that,” Ryan said.

He added that it’s unfair for a local brick and mortar retailer to have to collect sales taxes when online competitors are exempt.
