Here are reactions from two key voices, following Thursday night's briefing on the Syria situation by Obama administration officials.
Sen. Bob Corker of Tennessee, top Republican on the Senate Foreign Relations Committee:
"While I’m opposed to American boots on the ground in Syria, I would support surgical, proportional military strikes given the strong evidence of the Assad regime’s continued use of chemical warfare. Whatever limited action is taken should not further commit the U.S. in Syria beyond the current strategy to strengthen the vetted, moderate opposition,” said Corker.
“While the administration has engaged in congressional consultation, they should continue to be forthcoming with information and would be far better off if they seek authorization based upon our national interests, which would provide the kind of public debate and legitimacy that can only come from Congress.”
Here's House Democratic Leader Nancy Pelosi:This evening's briefing was informative and beneficial. For some of us, this was the third consultation with the Administration this week on the use of chemical weapons in Syria.
"On the call, I agreed with Speaker Boehner and other Members who stated that there needs to be more consultation with all Members of Congress and additional transparency into the decision making process and timing, and that the case needs to be made to the American people.
"It is clear that the American people are weary of war. However, Assad gassing his own people is an issue of our national security, regional stability and global security. We must be clear that the United States rejects the use of chemical weapons by Assad or any other regime.
"What Assad has done is outside the realm of basic human rights. On this evening’s call, I expressed my appreciation for the measured, targeted and limited approach the President may be considering.
"We were assured during the call there would be ongoing consultation with Congress."
