McMahon caused some controversy when he showed up to the Packers' reception at the White House wearing his Bears jersey, due to the rivalry between the two teams. McMahon later explained that he did so because he was unable to visit the White House when he led the Bears to victory in Super Bowl XX; two days after the Bears won the game, the crew of Space Shuttle mission STS-51-L were killed in the explosion of their craft, Shuttle "Challenger", and the Bears' scheduled visit was cancelled. McMahon and his surviving teammates and coaches were eventually received in 2011 by President Barack Obama, himself a Bears fan.
