WASHINGTON (AP) — The nation's largest gun-rights lobby says some participants at its White House meeting seemed more interested in demonizing the Second Amendment than keeping students safe.

The National Rifle Association met with Vice President Joe Biden's school safety study group on Thursday and afterward said the participants spent most their time on proposals to limit gun rights. The NRA says it, quote, "will not allow law-abiding gun owners to be blamed for the acts of criminals and madmen."

The politically powerful group — under public pressure since December's school shooting in Newtown, Conn., where a gunman massacred 20 children and six women — says it will now work with Congress to discuss what works in preventing violence and what does not.

The NRA previously proposed armed security in every American school.
