Obamacare could double healthcare premiums: Aetna CEO

To provide all Americans with health insurance, premiums will have to rise to pay for it, Aetna CEO Mark Bertolini told CNBC's "Closing Bell" on Wednesday. "If we're going to insure all Americans, which is a worthy and appropriate cause, then somebody has to pay for it," Bertolini said of the expected premium increases under Obamacare. Bertolini said that insurance premiums could double in some places just on the basis of what types of policies people buy today.
