Friday's shutdown showdown is about to get real — conservatives on both sides of the Capitol are privately plotting to force a government shutdown Friday in an effort to defund the Biden administration’s vaccine mandate on the private sector, multiple GOP sources told Playbook.

Capitalizing on a last-minute scramble to fund the government, a group of Senate conservatives is planning to object to quick consideration of a stopgap measure to extend funding into early 2022 unless Democratic leaders agree to deny money to enforce the mandate. Because of the tight schedule — and Senate rules that require unanimous consent to move quickly — the senators believe they’ll be able to drag out the process well past midnight on Friday, when funding officially expires.
