President-elect Joe Biden and Vice President-elect Kamala Harris vowed to protect American’s health care rights as COVID-19 cases rise around the world.

“We’re going to get right to work, I promise you,” Biden said Tuesday.

Biden and Harris addressed the media to discuss the Affordable Care Act as the Supreme Court hears a case that could potentially overturn the act, colloquially known as “Obamacare.”

If the ACA is overturned, it could do away with key protections for Americans with pre-existing health conditions and subsidized insurance premiums.

“Over 100 million people with pre-existing conditions like asthma, diabetes, cancer, could once again be denied coverage,” Biden said. “Complications from COVID-19 like lung scarring and heart damage will be the next flood of pre-existing conditions that could be used as an excuse to jack up premiums or deny coverage altogether for millions of survivors.”

Biden and Harris vowed to not only protect the ACA when they take office, but expand on it.

“My transition team will soon be starting its work to flesh out the details so that we can hit the ground running, tackling costs, increasing access, lowering the price of prescription drugs,” Biden said.

A decision on the Supreme Court case isn’t expected until late spring.
