Former President Obama said on Thursday that “The Affordable Care Act is here to stay.” 

In a series of tweets, Obama applauded the Supreme Court’s Thursday ruling upholding the act, saying it would ensure health insurance for millions.

“The principle of universal coverage has been established, and 31 million people now have access to care through the law we passed—with millions more who can no longer be denied coverage or charged more because of a preexisting condition,” Obama said.

Obama also said that he hopes President Biden will continue to “strengthen and expand” the measure, adding that Biden has extended the special enrollment period until Aug. 15 for families to sign up. 

“Now we need to build on the Affordable Care Act and continue to strengthen and expand it. That’s what @POTUS Biden has done through the American Rescue Plan, giving more families the peace of mind they deserve,” he said.
