A supporter of two Obamacare stabilization bills cited a new analysis showing premiums will decrease due to the legislation amid attacks from outside groups that call the bills “bailouts.”

Sen. Lamar Alexander, R-Tenn., pointed Monday to a new analysis from the consulting firm Oliver Wyman showing the two bills lower premiums by more than 40 percent on the individual market, which is used by people that don’t have insurance through the government or a job and includes Obamacare’s insurance exchanges. Alexander also bristled at the notion the two bills are a “bailout” for insurers, an attack leveled by outside conservative groups Monday.
