In an interview with The Hill on Wednesday, Rep. Alexandria Ocasio-Cortez (D-N.Y.) said that a plan to address climate change would have to come with a $10 trillion price tag "to have a shot."

Why it matters: Ocasio-Cortez catalyzed climate talks with her Green New Deal, which called for ambitious goals such as net-zero U.S. greenhouse gas emissions and de-carbonizing the economy. As 2020 approaches, most Democrats have had to answer to the Green New Deal's stances. Of the existing plans presented by presidential contenders, AOC says she likes Gov. Jay Inslee's plan for more than $5 trillion and Sen. Elizabeth Warren's $2 trillion proposal.

“It’s not popular, it’s not politically popular, people are going to call it unrealistic, and I just don’t think people understand how bad the problem is."
— Ocasio-Cortez said to The Hill

The freshman Democrat also said she likes Joe Biden's plan, but said his goals and timeline were not up to par.

The Supreme Court ruled early Tuesday that federal executions can resume, reversing a lower court decision and paving the way for the first lethal injection since 2003 to take place at a federal prison in Indiana, AP reports.

The big picture: A lower court had delayed the execution, saying inmates had provided evidence the government's plan to carry out executions using lethal injections "poses an unconstitutionally significant risk of serious pain."

More Republicans say they're wearing masks

Data: Axios/Ipsos poll; Chart: Andrew Witherspoon/Axios

Nearly two-thirds of Americans — and a noticeably increasing number of Republicans — say they’re wearing a face mask whenever they leave the house, according to the latest installment of the Axios-Ipsos Coronavirus Index.

Why it matters: A weakening partisan divide over masks, and a broad-based increase in the number of people wearing them, would be a welcome development as most of the country tries to beat back a rapidly growing outbreak.

Buildings are getting tested for coronavirus, too

Testing buildings — not just people — could be an important way to stop the spread of the coronavirus.

Why it matters: People won't feel safe returning to schools, offices, bars and restaurants unless they can be assured they won't be infected by coronavirus particles lingering in the air — or being pumped through the buildings' air ducts. One day, even office furniture lined with plants could be used to clean air in cubicles.
