Bloomberg Blasts NRA: 'Connecticut Is Because of Some of Their Actions'

While Bloomberg, who endorsed Obama for president, praised his decision to have Biden work on a plan, the mayor took Obama to task, saying in the last four years the president has "gone in the wrong direction" on guns.

"[President Obama] signed two pieces of legislation, one which lets you carry guns in national parks where our kids play," Bloomberg said. "And the other one, he signed a bill so that you can carry a gun on Amtrak. I assume that's to stop the rash of train robberies, which I thought stopped in the 1800s."

Several politicians have also vowed to introduce new gun control legislation when Congress starts a new session in January. But Bloomberg called Democratic Sen. Barbara Boxer's proposalthis week to make greater use of the National Guard to provide more safety in schools "ridiculous."

"You don't want your kids to think that everybody in America is a bad person and that we are locking ourselves down and that we live like we're in a prison," Bloomberg said. "Our National Guard has other things to do. Putting more guns in schools, I mean, the National Guard is not the answer to everything."
