• Rep. Mike Rogers, chairman of the House Select Committee on Intelligence, said he understands the citizenry's skepticism over military action and said it would be a "horrible mistake" to move ahead without winning '"enough votes" and "confidence" in Congress.
• Rogers said chemical weapons pose a "serious problem" and pointed to "national security consequences for the United States." He said Congress needs to focus on the "consequences of doing something and the consequences of not doing something."

• Sen. John McCain criticized Kerry's comment that a Syria strike would be "unbelievably small." In a Twitter message, McCain called the comment "unbelievably unhelpful."
He was referring to Kerry saying, "We're not going to war. We will not have people at risk in that way. We will be able to hold Bashar al-Assad accountable without engaging and troops on the ground or any other prolonged kind of effort, in a very limited, very targeted, very short-term effort that degrades his capacity to deliver chemical weapons without assuming responsibility for Syria's civil war. ... That is exactly what we're talking about doing. Unbelievably small, limited kind of effort."
