Meanwhile, the shutdown continues to wreak havoc on the basic functions of the U.S. government. Native American communities are reporting shortages of medicine as the Indian Health Service goes understaffed, while a federally funded food delivery program to Indian reservations has halted. Immigration courts have seen 20,000 cases per week added to an already record-high backlog. And the Transportation Security Administration said a man with a loaded pistol passed through airport security at Atlanta International Airport. TSA workers are being forced to work without paychecks, and hundreds have been calling in sick as the shutdown drags on.
