It is reported that they were married 46 years ago on April 19, 1969. http://www.boston.com/sports/footba...m_brady_wont_join_patriots_at_white_hous.htmlHe went to his parent's anniversary party. I'm sure they celebrated that event on the same date that they got married 50 years ago.
Several other players didn't go to the event but weren't mentioned as being racist or being disrespectful to the president. Guess why they weren't called out as being racists.
Still a good enough reason to skip the White House.
