Joe Biden, former vice president and 2020 Democratic presidential hopeful, said Friday he would bring back the individual mandate, the penalty for not having health insurance, which was a pillar of the Affordable Care Act.

"Yes, I'd bring back the individual mandate," Biden said in an interview on CNN. The individual mandate would be popular now, "compared to what's being offered," he added.

Biden played an integral part in crafting the ACA, commonly known as Obamacare. However, President Donald Trump eliminated the individual mandate in 2017 by signing the Republican tax bill, effective the 2019 tax year.

Nearly all of the Democratic presidential hopefuls support some kind of government health-care plan. While he does not support of "Medicare for All," Biden said people should have the option to buy into Medicare if they want it.

"If you provide an option for anybody who in fact wants to buy into Medicare for All, they can buy in," the Democratic presidential front-runner said.

Biden also took a nuanced approach Friday, saying he supports providing emergency health care for undocumented immigrants in the U.S.
