Senator Charles Schumer says he's fighting a piece of legislation that would override New York state's tough conceal and carry gun law.

At a news conference yesterday, Schumer said the measure, which was introduced by South Dakota Senator John Thune, would force communities to let people from other states where concealed weapons are legal carry them into states with tougher gun laws.

Schumer says the bill would allow someone to go to another state, get a license to conceal a gun, and then come back with it – putting New Yorkers' safety at risk.

"Right now you walk down the streets in New York or Nassau County or Westchester County, you can have the solace of knowing that if someone has a gun on them, they've gone through a rigorous background check," Schumer said. "After this law, you can have no such comfort."

Schumer says the legislation could be passed by the Senate as early as this week.

Mayor Michael Bloomberg, who has been outspoken about tougher gun laws, released a statement saying, "This misguided proposal would destroy the concealed carry and illegal possession laws crafted by dozens of states. This bill would frustrate the efforts of police and encourage the activities of illegal gun traffickers."
