This week's edition of The 45th newsletter.

The race is on for Republicans to claim the substantial legislative victory of an overhauled tax system, while rushing to prevent a government shutdown on December 8.

The US Senate took a big step forward on Tuesday when the Budget Committee voted to pass the Republicans’ US$1.5 trillion tax package, clearing the way for the full Senate to vote on the bill later this week. President Trump and GOP congressional leaders have repeatedly said they want to approve a bill cutting business tax rates and modifying individual tax rates by the end of the year.

Progress on keeping the government funded and preventing a shutdown is less assured. The latest shutdown threat stems from a September move by Congress to pass a short-term continuing resolution to keep the government going. Democrats and some moderate Republicans want to enact protections for hundreds of thousands of young immigrants who came to the United States illegally as children as part of the negotiations to pass the required budget measure. A range of legislative priorities mean there's little time to iron out a compromise in the next fortnight as the deadline approaches.
