U.S. Border Patrol agents who have been temporarily deployed to protect U.S. Immigration and Customs Enforcement facilities in Chicago and Portland will remain on the job if the government shuts down this week.

Border Patrol’s roughly 20,000 front-line agents will remain on the job if Congress fails to avert a government shutdown by Tuesday night, including agents who have been pulled from the border to help with security outside ICE detention buildings in Illinois and Oregon.
