The Senate passed its version of the GOP tax plan shortly before 2 am Saturday morning on a narrow, mostly party-line vote of 51-49. Bob Corker was the only Republican to vote against it (here's why). The final bill — released online around 9:30 pm Friday — included hundreds of billions of dollars of changes designed to win over holdouts like Susan Collins, Jeff Flake, Ron Johnson, and Steve Daines.

What to expect: This vote is a done deal now, but the final version of what might be America's next tax code isn't. The Senate will still have to negotiate a final version with the House, but even though there will be critical details to be worked out, it's hard to see the bill falling apart after it's gotten this far.

NASA confirms water exists on sunny parts of the Moon

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.

Vice President Mike Pence no longer plans to attend the Senate's final confirmation vote for Judge Amy Coney Barrett on Monday, following Senate Democrats' claims that his presence after possible exposure to the coronavirus would be a "violation of common decency," a Pence aide confirmed to CNN and Politico on Monday.

Driving the news: Five of Pence's aides were recently diagnosed with COVID-19, including his chief of staff, who is currently quarantining. Pence has continued his campaign travel despite his possible exposure, which goes against CDC guidelines.
