Now with the text out, the current plan puts the entire timeline – having lawmakers read the text, advancing it to the Rules Committee and getting to a floor vote – in the span of a week. With time no longer on their side, a failure at any stage could result in a shutdown.

Government shutdowns occur when the federal government stops all or some of its operations because of a funding gap. Shutdowns happen when Congress fails to pass a budget for the following fiscal year, according to the Brookings Institution.

Congress has until the end of the week to pass a bill that will keep the government funded and avoid a shutdown in the heart of tax season.
