Marco Rubio's spokesman, Alex Conant, indicates some give on possible gun legislation.
"In the aftermath of the unspeakable tragedy in Newtown, Sen. Rubio, like millions of Americans, is looking for public policy changes that would prevent such a horrible event from happening again.
He remains a strong supporter of the Second Amendment right to safely and responsibly bear arms. But he has also always been open to measures that would keep guns out of the hands of criminals and the mentally ill. The challenge with gun laws is that by definition criminals do not follow the law. For example, Connecticut's gun laws, some of the strictest in the nation, were not able to prevent this atrocity. Nevertheless, he supports a serious and comprehensive study of our laws to find new and better ways to prevent any more mass shootings."
