Portland, Oregon, recorded the poorest air quality in the world Tuesday, per IQ Air, as the West Coast wildfires burn across some 5 million acres.

Why it matters: The mega-fires have charred 3,154,107 acres in California, over 1 million in Oregon and more than 807,000 in Washington amid hazardous air conditions. Seattle has the world's third-worst air quality and Los Angeles the seventh, according to IQ Air. The blazes have killed at least 35 people and displaced tens of thousands. Thousands of structures have been destroyed.

Senate Majority Leader Chuck Schumer and Mitch McConnell's inability to quickly strike a deal on a power-sharing agreement in the new 50-50 Congress is slowing down everything from the confirmation of President Biden's nominees to Donald Trump's impeachment trial.

Why it matters: Whatever final stance Schumer takes on the stalemate, which largely comes down to Democrats wanting to use the legislative filibuster as leverage over Republicans, will be a signal of the level of hardball we should expect Democrats to play with Republicans in the new Senate.

President Biden will seek a five-year extension of the New START nuclear arms control pact with Russia before it expires on Feb. 5, senior officials told the Washington Post.

Why it matters: The 2010 treaty is the last remaining constraint on the arsenals of the world's two nuclear superpowers, limiting the number of deployed nuclear warheads and the bombers, missiles and submarines which can deliver them.
