Former Vice President Joe Biden has earned endorsements from a string of prominent Democrats in the hours leading up to Super Tuesday, where wins in huge delegate states like California and Texas could drastically change the trajectory of the 2020 race.

Driving the news: Two former Obama administration officials — former UN Ambassador Samantha Power and former White House chief of staff Denis McDonough — endorsed Biden on Tuesday.

But they're not the only big names throwing their weight behind Biden's campaign, which has seen a turnaround after a sweeping victory in South Carolina overshadowed his poor performances in Iowa and New Hampshire. Other political figures endorsing Biden on Monday and Tuesday include:

  • Pete Buttigieg
  • Amy Klobuchar
  • Beto O'Rourke
  • Former Senate Minority Leader Harry Reid
  • Former UN ambassador and Obama national security adviser Susan Rice
  • Illinois Sen. Tammy Duckworth
  • California Rep. Gil Cisneros
  • Texas Rep. Veronica Escobar
  • Ohio Rep. Marcia Fudge
  • Former Colorado Sen. Mark Udall
  • Austin Mayor Steve Adler
  • Virginia House Majority Leader Charniele Herring
  • Denver Mayor Michael Hancock
  • Chattanooga Mayor Andy Berke
  • Florida Rep. Debbie Wasserman Schultz

The big picture: Moderates are coalescing around Biden in a bid to stop progressive Sen. Bernie Sanders, who could run away with an insurmountable delegate lead after Super Tuesday. Mike Bloomberg, a centrist who will appear on the ballot for the first time on Tuesday, doesn't yet appear to be budging.

A former Georgetown University head tennis coach has pleaded guilty Tuesday to bribery charges related to facilitating the admission of prospective applicants.

Why it matters: Gordon Ernst solicited and accepted bribes from William Singer, ringleader of the cheating scheme uncovered by Operation Varsity Blues, and families in exchange for helping prospective applicants get into Georgetown as student athletes, according to the Justice Department.

The Centers for Disease Control and Prevention said in updated guidelines Tuesday that some immunocompromised people who have received either Pfizer or Moderna's COVID-19 vaccines will be able to get a fourth shot.

Details: People over 18 who are "moderately to severely immunocompromised" and have received three doses of an mRNA vaccine may get a fourth shot (of either the Pfizer, Moderna, or Johnson & Johnson vaccines) at least six months after getting their third Pfizer or Moderna dose, per the CDC.

Scoop: Biden plan expected to include at least $500B for climate

Photo: Stephanie Keith/Bloomberg via Getty Images

The White House is privately telling lawmakers the climate portion of President Biden's roughly $2 trillion social spending plan is "mostly settled" and will likely cost more than $500 billion, two sources familiar with the talks tell Axios.

Why it matters: A price tag of $500 billion to $555 billion is a huge number and, if it holds, would likely be the single biggest component of the sweeping package. It also isn't far off from the roughly $600 billion proposed when the bill was expected to cost $3.5 trillion.
