Swedish teenage climate activist Greta Thunberg endorsed Joe Biden in a tweet Saturday aimed at driving turnout in the election.

Why it matters: The 17-year-old Thunberg is among the world's highest-profile advocates for aggressive steps to combat global warming.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.

Quick take: Thunberg's backing underscores how left activists are consolidating around Biden, despite some groups' misgivings about his platform.

  • He's picked up endorsements from groups on the left flank of the green movement, such as Oil Change U.S. and the political arms of 350.org and Friends of the Earth.
  • Biden's platform has grown more aggressive in recent months, but still doesn't contain elements that many environmental activists want — notably a call to ban fracking.

Biden outlines plan to reverse Trump policies on first day of presidency

President-elect Joe Biden will roll back some of President Trump's most controversial policies and address "four overlapping and compounding crises" in his first 10 days in office — the pandemic, the economic downturn, climate change and racial inequity.

Driving the news: The plan is outlined in a memo from incoming White House Chief of Staff Ron Klain Saturday. Following Biden's inauguration Wednesday, he'll "sign roughly a dozen actions to combat the four crises," Klain said.

How GameStop exposed the market

Retail traders have found a cheat code for the stock market, and barring some major action from regulatory authorities or a massive turn in their favored companies, they're going to keep using it to score "tendies" and turn Wall Street on its head.

What's happening: The share prices of companies like GameStop are rocketing higher, based largely on the social media organizing of a 3-million strong group of Redditors who are eagerly piling into companies that big hedge funds are short selling, or betting will fall in price.

Who benefits from Biden's move to reopen ACA enrollment

Nearly 15 million Americans who are currently uninsured are eligible for coverage on the Affordable Care Act marketplaces, and more than half of them would qualify for subsidies, according to a new Kaiser Family Foundation brief.

Why it matters: President Biden is expected to announce today that he'll be reopening the marketplaces for a special enrollment period from Feb. 15 to May 15, but getting a significant number of people to sign up for coverage will likely require targeted outreach.
