The Sunrise Movement, a collective of young people advocating for action on climate change, announced Thursday that it is endorsing Bernie Sanders in the 2020 presidential election.

Why it matters: Young people are the demographic leading the charge against climate change, which has been at the forefront of Democratic policy proposals this cycle. The group said it endorsed Sanders for his decision to spearhead the Green New Deal — along with his top surrogate, Rep. Alexandria Ocasio-Cortez (D-N.Y.).

Biden on Supreme Court fight: "This is about whether or not the ACA will exist"

Joe Biden made health care the overwhelming focus of his remarks from Wilmington, Delaware, on Sunday, stressing that the Senate confirmation battle over Judge Amy Coney Barrett's nomination to the Supreme Court is about preserving the Affordable Care Act in the midst of a pandemic.

McMaster: Trump's peaceful transition comments are a "gift to our adversaries"

President Trump's refusal to commit to a peaceful transfer of power if he loses November's presidential election is a "gift to our adversaries," Trump's former national security adviser H.R. McMaster said Sunday.

Trump's Supreme Court pick, Amy Coney Barrett, has written that she disagreed with Chief Justice John Roberts when he ruled to uphold the law.
