The way things are going in Congress, the Department of Homeland Security could be lucky if it gets just enough funding next week so it doesn’t have to shut its doors. But in reality, a continuing resolution is just about the worst way that Congress could solve the funding problem, short of actually shutting the department down. Customs and Border Protection wouldn’t be able to upgrade its mobile video systems to patrol the Rio Grande Valley. The Federal Emergency Management Agency wouldn’t be able to write the grants that pay the salaries of state and local emergency management officials. It might also have to cancel a series of training workshops next month for first responders.
