The Columbia Missourian reports the fan reaction came during a break in Saturday’s Missouri-Tennessee game. Booing broke out when the new Guard members were instructed as part of their sworn oath to “obey the orders of the president of the United States.”

Student Julia Bosley says she’s disappointed that university officials didn’t ask those booing to stop.

State Rep. Clem Smith, of suburban St. Louis, said Monday he attended the game and heard jeers from crowd members “disrespected the proud men and women of our nation’s great military.”
