President Obama keep his promise and oath of office.

At a televised campaign event in Lebanon, Virginia in 2008, Obama stated;
"When you all go home and you're talking to your buddies and you say, ah 'He wants to take my gun away.' You've heard it here; I’m on television so everybody knows it. I believe in the Second Amendment. I believe in people's lawful right to bear arms. I will not take your shotgun away. I will not take your rifle away. I won't take your handgun away."
The President also took an oath of office;
“to the best of my Ability, preserve, protect and defend the Constitution of the United States."
He publicly announced an attack on the 2nd Amendment, choosing to violate his oath. I suggest as an honorable man, if unable to keep his promise or more importantly his oath of office, to please step down.
