Commonwealth Fusion Systems, a Cambridge, Mass.-based startup focused on commercializing fusion energy, raised $115 million in Series A funding.

Why it matters: Nuclear fusion, the process of combining hydrogen atoms rather than splitting them, has long been the clean energy industry's holy grail, promising unlimited output without creating any carbon emissions or nuclear waste.

  • CFS, spun out of MIT, claims it could have demonstrations by 2021 and a full facility prototype by 2025.
  • Investors: Future Ventures, Khosla Ventures, Lowercase Capital, Moore Strategic Ventures, Safar Partners, Schooner Capital, Starlight Ventures, Breakthrough Energy Ventures, Eni and The Engine.

The bottom line: Stay skeptical, as there are scientific and cost reasons why no one has successfully commercialized nuclear fusion, but this is a well-funded moonshot that's worth watching.

Vaccine distribution, pandemic data and a cross-party comity dominated today's virtual meeting between White House officials and a bipartisan group of 16 senators, Senator Angus King told Axios.

Why it matters: Given Democrats' razor-thin majority in both chambers of Congress, President Biden will have to rely heavily on this group of centrist lawmakers — dubbed the "Sweet 16" — to pass any substantial legislation.

Progressives pressure Schumer to end filibuster

A progressive coalition is pressuring Chuck Schumer on his home turf by running a digital billboard in Times Square urging the new majority leader to end the Senate filibuster.

Why it matters: Schumer is up for re-election in 2o22 and could face a challenger, and he's also spearheading his party's broader effort to hold onto its narrow congressional majorities.

The U.S has confirmed more than 25 million coronavirus cases, per Johns Hopkins data updated on Sunday.

The big picture: President Biden has said he expects the country's death toll to exceed 500,000 people by next month, as the rate of deaths due to the virus continues to escalate.
