A Michigan State University economics professor discovered $21 trillion unaccounted for in the federal budget starting in 1998 until the end of fiscal year 2015. Professor Mark Skidmore enlisted the help of his graduate students to examine government documents from the Department of Defense and Housing and Urban Development to uncover an unfathomable amount of unauthorized spending.

According to the Constitution, all federal spending must be voted on and authorized by Congress each fiscal year. Any discrepancies found in the way of unauthorized spending would normally elicit a congressional hearing and investigation.
