Mitt Romney's son, Tagg, says he had the urge to take a swing at President Obama when the Chief Exec called his dad a liar.
Tagg made his comment on a radio show, when asked how it felt to hear Obama accuse his father of fibbing.
As for why Tagg resisted ... his first reason -- lots of secret service around. Tag went on to say ... accusations of lying are all part of the political process.
