3rd Democratic senator calls on Biden to step aside
Sen. Martin Heinrich of New Mexico, became the third sitting Democratic senator to call on Biden to end his reelection bid.
Heinrich said in a statement Friday, "this moment in our nation's history calls for a focus that is bigger than any one person," citing a possible Trump victory.
"By passing the torch, [Biden] would secure his legacy as one of our nation's greatest leaders and allow us to unite behind a candidate who can best defeat Donald Trump and safeguard the future of our democracy," he added.
