A whopping $21 trillion was found to be missing from the US federal budget as of this past year. Michigan State University professor Mark Skidmore and a group of graduate students made the discovery after overhearing a government official say that the 2016 report by the Department of Defense’s Office of Inspector General (DoDIG) indicated $6.5 trillion in adjustments had not been adequately documented. Attempting to uncover the reasoning behind these adjustments, Skidmore began to dig deeper. He says, “I tried to call and talk to the office of the Inspector General to talk to the people who helped generate these reports. I haven’t been successful, and I stopped trying when they disabled the links.”
