The group is one of several task forces being formed to bridge the divide between the polices of Biden and Vermont Sen. Bernie Sanders, who ended his White House bid last month.
"I'm working with Bernie and with his people. And so, and we've made some changes. We've listened to Bernie supporters and, you know, for example, we have Congresswoman Ocasio-Cortez, she is on one of the panels," Biden said Tuesday in an interview with News8 in Las Vegas.
Ocasio-Cortez spokeswoman Lauren Hitt said in a statement that the congresswoman made the decision to join the task force "with members of the Climate Justice community - and she will be fully accountable to them and the larger advocacy community during this process."
