On December 2, 2009, Norton had an on-air argument with Jesse Ventura about the September 11 attacks and measures against illegal immigration. Ventura was arguing against what Norton claimed was the Border Patrol practice of stopping individuals and asking them to produce ID deep within US borders, claiming that such actions were unconstitutional. At some point, when Norton disagreed with him on this, Ventura suggested that Norton did not believe in the Constitution to which Norton strongly objected. Soon after, as the argument became more heated, Ventura walked off the air and the two exchanged explicit comments towards each other.
