Massachusetts Sen. Elizabeth Warren officially endorsed former Vice President Joe Biden Wednesday after fellow progressive Sen. Bernie Sanders of Vermont and former President Barack Obama gave their endorsements this week.

“Empathy matters, and in this moment of crisis, it’s more important than ever that the next president restores Americans’ faith in good, effective government,” Warren said in video posted on Twitter. “Joe Biden has spent his entire life in public service. He knows that a government run with integrity, competence, and heart will save lives and save livelihoods.”

On Monday, Sanders made his endorsement appearing in a live-stream with Biden less than a week after ending his own campaign as the Democratic frontrunner’s final remaining major competitor in the race. Sanders was followed quickly by Obama on Tuesday, who endorsed his former vice president of eight years after all other options were eliminated.

Warren’s endorsement Wednesday marks the continuation of Democrats’ efforts to unite a fractured party emerging from a divisive primary that included more than 25 major candidates seeking the party’s coronation in Milwaukee this summer.

The Massachusetts senator ended her own campaign in early March after failing to capture a single first-place victory in any state contest, and placing third in her home state. While her fellow progressive senator who had been much of an ally throughout the primary campaigned head-to-head against Biden, Warren refrained from endorsing Sanders. The recent series of endorsements come as a welcome relief to the Biden campaign and an anxious Democratic Party concerned whether a broad coalition will come together in their quest to topple President Donald Trump from the Oval Office this fall.
