Aurora shooting highlights gun debate

Friday's deadly movie theater shooting rampage in Colorado is raising new talks of beefing up the nation's gun laws.

But not everyone is on board.

New Jersey Gov. Chris Christie calls it "political grandstanding.” The Republican said he agrees with President Obama, saying this is not the time to push for new regulations.

Christie said there are already sufficient weapons laws on the books.

"It’s time for us to aggressively enforce the gun laws that we have,” said Christie. “I am a little bit disturbed by politicians who in the immediate aftermath of this type of tragedy try to grandstand on it, and I’m not going to be one of those people."

Twelve people were killed and 58 hurt when a gunman burst into The Dark knight Rises early Friday and opened fire.

The suspect, 24-year-old James Holmes, is being held behind bars in isolation. He made an appearance in court Monday for his hearing and appeared to be in a daze.

Holmes is set to make another court appearance next week.
