“The House and Senate are back in session Sunday with a federal government shutdown in its second day amid a spending-bill impasse in Congress. The House is supposed to be on recess this week, but members stayed in Washington as negotiations continue. Publicly, Senate Majority Leader Mitch McConnell and Minority Leader Chuck Schumer are dug in to their opposite positions. Behind the scenes, a senior House Republican said Saturday that vote-counters were being told a deal could be reached Sunday to reopen the government. Failing that, McConnell threatened a 1 a.m. vote Monday on his proposal to fund the government for three weeks, with no action on Democrats’ immigration proposal.” https://www.bloomberg.com/news/articles/2018-01-20/lawmakers-point-fingers-with-no-plan-in-sight-shutdown-update

Worth noting that if it fails and they do squeeze through a 3 week extension the front month /VX future expires in 23 days so I doubt we’d see a significant front month vol crush as a result of the deal.
