"We'll be able to get to an agreement," Senate Majority Leader Mitch McConnell told ABC's "This Week." "I'm very optimistic about it."
McConnell says his party will come to an agreement before Christmas.
There'll definitely be a lot to unpack before then. We've covered the differences between the House and Senate versions. One sticking point is the number of individual income tax brackets. Today, there are seven, and the Senate bill keeps it that way — whereas the House version creates just four brackets, starting at 12 percent and going up to 39.6 percent.
So it'll be a busy week for Congress. While work on the tax overhaul is ongoing, members also face a looming deadline. By Friday they need to pass a spending plan to avoid a government shutdown.
