Rand Paul urges caution on Syria: ‘We should ascertain who used the weapons’

Sen. Rand Paul (R-Ky.) is out with a brief statement on the situation in Syria, calling for a cautious approach and congressional approval for any military action.

He also appears to question the administration's assertion that the Syrian regime definitely used chemical weapons. Vice President Biden has said there is "no doubt" that it did.

"We should ascertain who used the weapons and we should have an open debate in Congress over whether the situation warrants U.S. involvement," Paul said. "The Constitution grants the power to declare war to Congress, not the President."
