Ocasio-Cortez earlier this year endorsed the Vermont senator for president in the 2020 election, and is a proponent of progressive policies espoused by the candidate such as "Medicare for All" and the Green New Deal.

The former vice president has been vocal in warning against switching to a Medicare for All system, instead pushing for expanding the Affordable Care Act and adding a “public option” that allows people to select a government plan or use private insurance.

Biden said earlier this week that the majority of enthusiasm among Democrats was not behind Medicare for All.

"I don’t think the bulk of the enthusiasm in the Democratic Party is for Medicare for All," he said.

However, Biden has not only been in conflict with Sanders and Warren over the issue.
