Former vice president and 2020 Democratic presidential hopeful Joe Biden on Thursday reversed a pledge not to accept the help of super PACs. A Biden campaign spokesperson said the move was necessary to counter a barrage of attack ads from President Trump. A spokesperson for Bernie Sanders’s campaign — which opposes super PACs — slammed Biden’s move, saying, “Joe Biden has spent his campaign promising elite donors that nothing will fundamentally change for them, and he has made clear to fossil fuel and pharmaceutical donors that he will be their ally.”
