"Democrats slam GOP healthcare proposal as Obamacare premiums & deductibles increase by over 100%. Remember keep your doctor, keep your plan," the president wrote in an early morning tweet.
Senate Republicans unveiled their plan to repeal Obamacare — the Better Care Reconciliation Act — on Thursday. The bill needs 50 votes to pass but lacks the support of Senate Democrats and several Republican lawmakers.
According to new analysis released last week by Oliver Wyman Health, an actuarial firm, premiums could increase by 40 percent by 2018 under Obamacare.
On Saturday evening, Trump seemingly went after lawmakers of his own party for holding up the bill's passage.
