(CNN) - Let's start with the obvious question: Will the government shut down this week? Most likely.
Republicans and Democrats can agree on that. It's everything else that has them bickering and blaming. And unless they strike a deal on a spending bill Monday, the government will begin closing shop at 12:01 a.m. Tuesday.
After weeks of congressional back-and-forth, the ball is now in the Senate's court. It meets at 2 p.m. Monday to decide what to do next.
A shutdown, while likely, isn't a foregone conclusion. The deadline is midnight - and one day can be a long time on Capitol Hill.
Here's a quick Q&A to get you caught up on what happened over the weekend and what to look forward to Monday.
Tonight in the Crossfire: hours away from a potential government shutdown, Andrew Roth, Vice President of Government Affairs for Club for Growth, and Brad Woodhouse, President of Americans United for Change and former DNC spokesman, join hosts Newt Gingrich and Van Jones.
