With the fate of gun control legislation in doubt, Sen. Rand Paul (R-Ky.) accused President Obama of using the victims of the Newtown elementary school shootings as "props" to advance an agenda that would have done nothing to prevent the massacre.

"I think gun control is a legitimate issue for our country to debate," he said at a Christian Science Monitor breakfast Wednesday morning. But the Kentucky senator said that looking at the parents of Newtown victims who have spoken in favor of gun control legislation, "I think in some cases the president has used them as props."
