Mayor Michael Bloomberg is pushing President Barack Obama and GOP challenger Mitt Romney to make specific recommendations — such as banning assault riffles — for how to change the nation's gun laws in the mass shooting in Colorado that left 12 dead and 58 injured.
Speaking on "Face the Nation" on CBS Sunday morning, Bloomberg took aim at the National Riffle Association and put the onus of gun reform on the White House.
"We have federal laws that say you can not sell guns to minors, to people with psychiatric problems, or drug problems, or convicted felons," the mayor said, "and yet they pressure Congress and the White House to not fund enforcement of those laws."
Bloomberg founded and co-chairs Mayors Against Illegal Guns, and said the presidential candidates should support re-instating the federal ban on assault rifles, and better enforce the gun control laws already on the books.
He urged the White House to support a ban on assault rifles, one of the guns allegedly used by the 24-year-old gunman when he sprayed a crowded movie theater with bullets early Friday.
"Weapons that are sold, advertised as high capacity, and very powerful aren't weapons that are to be used in hunting and they certainly aren't weapons to be used to defend yourself," he said.
Bloomberg said Romney passed a ban on assault weapons when he was governor of Massachusetts, and as a presidential candidate Barack Obama said he would work to reinstate such a ban on the federal level, but that neither candidate now seems to support it.
