WASHINGTON (AP) -- Members of Congress, abruptly handed exactly the war powers many had demanded, grappled Saturday with whether to sign off on President Barack Obama's plan to punish Syria for an alleged chemical weapons attack. Now with a stake in the nation's global credibility, lawmakers were seeking more information about the possible consequences of striking a region without knowing what would happen next.
The debate over what action, if any, Congress might approve is in its infancy as lawmakers prepare for a public hearing Tuesday by the Senate Foreign Relations Committee. But the first contours began emerging within hours of Obama's announcement.
Sen. John Cornyn, R-Texas, said he doesn't believe Syria should go unpunished for the Aug. 21 attack near Damascus. "But we need to understand what the whole scope of consequences is," he said by telephone. "What the president may perceive as limited ... won't stop there."
Arguing for a strategy that seeks to end Syrian President Bashar Assad's rule, Sens. John McCain of Arizona and Lindsey Graham of South Carolina issued a joint statement saying that any operation should be broader in scope than the "limited" scope Obama described.
"We cannot in good conscience support isolated military strikes in Syria that are not part of an overall strategy that can change the momentum on the battlefield, achieve the president's stated goal of Assad's removal from power, and bring an end to this conflict, which is a growing threat to our national security interests," the senators said.
"Anything short of this would be an inadequate response to the crimes against humanity that Assad and his forces are committing. And it would send the wrong signal to America's friends and allies, the Syrian opposition, the Assad regime, Iran, and the world - all of whom are watching closely what actions America will take," they said.
Lawmakers of both parties had, for days, demanded that Obama seek congressional authorization under the War Powers Act. Until Saturday, the president showed no willingness to do so and the military strike appeared imminent. Then, from the White House Rose Garden, Obama said he would strike Syria in a limited way and without boots on the ground. But, he added, he would seek congressional approval first.
"All of us should be accountable as we move forward, and that can only be accomplished with a vote," Obama said. "And in doing so, I ask you, members of Congress, to consider that some things are more important than partisan differences or the politics of the moment."
With that, Obama dropped the question of Syria, the nation's credibility and the balance of government power in the very laps of lawmakers who had complained about his go-it-alone-style -- but were less clear about how they would want to deal with a horrific chemical attack that the administration said killed 1,429 people, including 426 children. Other estimates of the death toll were in the hundreds.
By evening Saturday, the White House sent Congress its draft of a resolution to authorize Obama to use military force. The draft does not lay out a specific timeline or course of military action but gives Obama approval to use the military as he determines "necessary and appropriate" to meet its objective of preventing further chemical attacks. It also affirms the administration's view that, ultimately, only a negotiated political settlement can resolve the crisis in Syria.
An aide to House Speaker John Boehner, R-Ohio, confirmed that the speaker's office had received the draft.
A hearing before the Senate Foreign Relations Committee plus classified and unclassified briefings for senators were being scheduled, Senate Majority Leader Harry Reid, D-Nev., said Saturday. Sen. Robert Menendez, D-N.J., the chairman of the Foreign Relations Committee, said the hearing would take place Tuesday.
Both the Senate and the House planned a vote on the matter no later than the week of Sept. 9.
There's little doubt that Obama as commander in chief could retaliate against Syrian targets without approval from the American people or their representatives in Congress. He did it two years ago in Libya, but in that case, the U.S. led a NATO coalition.
Congress' constitutional power to declare war was refined and expanded by the 1973 War Powers Act, which requires a president to notify Congress within 48 hours of initiating military action and bars U.S. armed forces for fighting for more than a maximum of 90 days without congressional approval. President Richard Nixon vetoed that bill, but Congress overrode the veto.
Even with that power, Congress hasn't formally declared war since World War II.
