Sen. Ron Johnson, R-Wis., said Tuesday he is working with the White House as well as House and Senate lawmakers to make changes to a bipartisan Obamacare stabilization bill.

Both President Trump and House Republicans are opposed to a Senate bill that would fund Obamacare insurer payments for two years in exchange for flexibility to states to waive the law’s insurance regulations. Johnson said Tuesday that bill wouldn’t mean much if it all it could do is pass the Senate.
