 Homeland Security says border arrests fell significantly since Biden's halt to asylum processing. Donna Warder reports. The Department of Homeland Security says during the past three weeks, average daily arrests for crossing into the U.S. illegally have dropped by more than 40 percent. That's below 2,400 arrests in a day. Under a proclamation that took effect June 5th, asylum processing is suspended when daily arrests are below 2,500.
