Sen. Elizabeth Warren (D-MA) endorsed presumptive nominee Joe Biden for President Wednesday morning.

In a stirring video, Warren painted him as the figure who, by a combination of personal empathy and experience with leading the U.S. through a financial recovery, is well-poised to take over in November.

“He knows that a government run with integrity, competence and heart will save lives and livelihoods,” she said. “And we can’t afford to let Donald Trump continue to endanger the lives and livelihoods of every American.”

Alluding to the current economic slump born from the coronavirus pandemic, she pointed to his work leading the financial recovery in 2009 and setting up her Consumer Financial Protection Bureau.

She said she watched his emotional leadership “up close” when he comforted the people of Boston after the 2013 marathon bombing.

“And now, it’s up to all of us to to help make Joe Biden the next president of the United States,” she said. “Let’s get to work.”

Warren’s endorsement comes hot on the heels of former President Barack Obama’s and Sen. Bernie Sanders’ (I-VT).

After she first dropped out of the race in early March, there was rampant speculation about which of the remaining two candidates she’d support: Sanders, with whom she was more ideologically aligned but whose campaign clashed with hers, or Biden, the clear frontrunner. She declined to back either horse at the time.

Now, Biden has scooped up the support of all of his most formidable former competitors, moderates and progressives alike. With Sanders out of the race, he has pivoted to the general election and struck a tone of unity in an attempt to bring together the wings of the party.
