Minnesota U.S. Sen. Amy Klobuchar will debate the Democratic side of health care policy Monday evening on CNN, the cable station said.

On the Republican side: U.S. Sens. Lindsey Graham, of South Carolina, and Bill Cassidy, of Louisiana. The two Republicans are working to shepherd through a repeal of the federal Affordable Care Act, known as Obamacare.

Vermont U.S. Sen. Bernie Sanders, an independent who has been pushing single-payer health care, will round out the quartet. Minnesota U.S. Sen. Franken has supported the single-payer bill but Klobuchar has not.

“The town hall debate will air on CNN, CNN en Español and CNN International as well as stream live for subscribers on CNNgo and the CNN mobile apps for iOS and Android. The town hall debate will also air on CNN’s SiriusXM Channel 116,” CNN said. It will air at 8 p.m. Central time.

Klobuchar, who is occasionally mentioned as a possible 2020 presidential candidate, has said that the Republican health insurance bill would result in “chaos” and that “bipartisan work to fix ACA (is) again stymied by partisan efforts to repeal.”

The Minnesota governor’s office said this week that the measure, known as Graham-Cassidy, would cause the state to lose $31 billion in federal Medicaid funding by 2030, eliminate federal funding for MinnesotaCare and put caps on health care spending for seniors, people with disabilities and families with children.

President Donald Trump and other Republicans have been urging senators to support the measure in order to undo the Obama-era health care law. It might receive a full vote in the U.S. Senate next week.

This summer an earlier iteration of the Obamacare repeal failed to receive enough votes to pass the Senate. The U.S. House has already approved a repeal measure.
