Chelsea Clinton said Sanders would also “dismantle Medicare and dismantle private insurance,” as well as strip away benefits from the Children’s Health Insurance Program, which was created under her father’s presidency.

“I worry if we give Republicans Democratic permission to do that, we'll go back to an era — before we had the Affordable Care Act — that would strip millions and millions and millions of people off their health insurance,” she said.

Sanders, who voted for the Affordable Care Act, has previously written off Hillary Clinton’s attacks that he would undo ObamaCare.

“I helped write the Affordable Care Act. So I don’t want somebody suggesting I’m trying to dismantle legislation that I helped write,” Sanders said last November.

The Clinton campaign has been sharpening its attacks on Sanders ahead of Iowa's Feb. 1 caucuses. Chelsea Clinton will join her parents in the state next week.
