Homeland Security Secretary Markwayne Mullin warned over the weekend that his agency faces sweeping staffing challenges as it seeks to rebound from a historic shutdown. 

The DHS’s 76-day shutdown ended on April 30 after it set a record for the longest government shutdown in U.S. history. In the aftermath of the shutdown, which was sparked due to Democrats’ concerns about Immigration and Customs Enforcement and Border Patrol, Mullin said the DHS’s Cybersecurity and Infrastructure Security Agency had lost over 1,000 employees due to the debacle.
