Infighting at the White House ... and it's all over Super Bowl LII!
Don't worry, it's all in good fun -- but Kellyanne Conway says she's got an enemy at 1600 Pennsylvania Ave. for the next week ... Trump's chief of staff, Gen. John Kelly!

Gen. John Kelly is a South Boston guy ... he's ride or die Tom Brady.
The big question .
