“Biden will be a much-needed stabilizing force following Trump’s disastrous term, offering a positive and progressive alternative to Trump’s dark vision of racism, xenophobia and policies built on cruelty and exclusion. I believe Biden is best able to defeat Donald Trump and enact the policies we all care about.”

Reid’s high-profile endorsement followed a wave of incoming support for Biden a day before the crucial Super Tuesday races, including from his former opponent Sen.

Sanders’s campaign manager Faiz Shakir called Reid’s endorsement “disappointing.”

“Disappointing. I'll forever have respect and love for Senator Reid. But I'm old enough to remember when he thought Biden's ideas were worthy of being put in a fireplace,” Shakir, who used to work for Reid, tweeted with a link to a HuffPost story from 2013 about then-Majority Leader Reid.
