House Speaker Mike Johnson on Sunday said he believes he has the votes to end the partial government shutdown by Tuesday, with the House set to take up a Senate-approved spending package this week.

“Let’s say I’m confident that we’ll do it at least by Tuesday,” the Louisiana Republican said on NBC’s “Meet the Press.”

The U.S. government partially shut down on Saturday morning after Congress failed to approve a spending package and send it to President Donald Trump by the Jan. 30 deadline.

Senate Democrats demanded changes to the package that the House originally passed after two U.S. citizens were shot and killed by federal immigration agents in Minnesota. Democrats ultimately had the Department of Homeland Security funding stripped from the package and replaced with a two-week stopgap. Now, the amended package has to be reapproved by the House.

The House is set to begin taking up the bill on Monday. The House Rules Committee is scheduled to meet on Monday, the first step in that process.
