Obama is scheduled to "deliver remarks celebrating the success of the Affordable Care Act and Medicaid in extending affordable health insurance to millions of Americans as part of the President's agenda to cut costs for American families," according to a White House agenda seen by the Hill.

Ongoing efforts to strengthen the act are expected to be touched on, adding to a policy first signed 12 years ago during Obama's first term in office.

"Twelve years ago, I proudly stood beside President Barack Obama as he signed into law the most consequential expansion of health care in generations: the Affordable Care Act," Biden said in a statement marking the anniversary of the policy.

"With the stroke of a pen — after decades of tireless efforts — millions of Americans gained peace of mind. And because of my Administration's efforts, including passing the landmark American Rescue Plan, we have lowered health care costs and made coverage more accessible than ever before — even amid a global pandemic," the president added.
