Joe Biden taps AOC to lead campaign's climate change task force

Democratic presidential candidate Joe Biden said on Tuesday that Rep. Alexandria Ocasio-Cortez (D-N.Y.) is working with the Biden campaign to promote her "Green New Deal." 

What are the details? 

According to a CNN report, the democratic socialist will "co-chair a task force" for the Biden campaign centered on climate change. 

The move, according to the outlet, is intended to add "progressive credentials to the former vice president's effort to unify the party ahead of the general election."
