House Speaker Nancy Pelosi on Monday endorsed former Vice President Joe Biden for president as Democrats continue to coalesce around their presumptive nominee and drum up enthusiasm for all federal races ahead of the November election.

In a Monday video posted to Twitter, the California Democrat praised Biden's experience while serving in the Obama administration, touting his work on economic recovery during the Great Recession and for helping Democrats pass the Affordable Care Act in 2010. Since the 2018 election cycle, the party has campaigned heavily on protecting health care benefits established by the ACA as President Donald Trump and Republicans seek to gut the law.

"When the Trump administration launched its campaign to destroy every last benefit and protection of the ACA, Joe Biden has been with us every step of the way to protect Americans' quality, affordable health care," Pelosi said. "And as we face coronavirus, Joe has been a voice of reason and resilience with a clear path to lead us out of this crisis."

Pelosi is the latest high-profile Democrat to formally throw her support behind Biden, coming a couple of weeks after prominent endorsements from former President Barack Obama as well as Biden's former Democratic rivals, Sen. Bernie Sanders of Vermont and Sen. Elizabeth Warren of Massachusetts.

And as Biden looks to unify the party since Sanders' departure from the race earlier this month, he has sought to shore up support from the progressive wing of the party. He's gotten recent endorsements from a handful of members from the Congressional Progressive Caucus, including former Sanders' national campaign co-chairman Rep. Ro Khanna of California and CPC co-chairs Rep. Pramila Jayapal of Washington and Rep. Mark Pocan of Wisconsin. And Rep. Alexandria Ocasio-Cortez of New York has said she'll vote for Biden in November.

Pelosi also called on Americans to vote in November not just for Biden, but for Democrats running in down-ballot races as they seek full control of Congress. Democrats are looking to protect their House majority and to also gain a few seats in the Senate to regain control of the chamber. Republicans still hold an overall advantage in keeping their narrow majority, but Democrats' prolific fundraising and candidate recruits have recently bolstered their odds.
