The clock is ticking toward a September 30 deadline to fund the government, and even with a possible deal to avert a lapse in funding, parts of the US government will start the behind-the-scenes process of preparing for a potential shutdown.

The announcement comes after the House voted 202-222 last week against a spending plan through the end of March and also included a GOP-backed provision that would have mandated proof of citizenship when registering to vote in a nod to Trump’s baseless claims that non-citizens voting in elections has led to fraudulent votes for Democrats.

Congressional leaders have a deal on a short-term spending bill that will fund federal agencies for about three months.
