WASHINGTON - President Barack Obama's call for a military strike in Syria won significant momentum Tuesday, with leaders of both parties in Congress announcing they are convinced that Syrian President Bashar Assad used chemical weapons against his own people and that the United States should respond.
Republican House Speaker John Boehner emerged from a White House meeting and told reporters: "This is something that the United States, as a country, needs to do. I'm going to support the president's call for action. I believe that my colleagues should support this call for action."
House Majority Leader Eric Cantor and House Democratic Leader Nancy Pelosi also said they will support Obama because the U.S. has a compelling national security interest to prevent the use of weapons of mass destruction.
But their endorsements still don't resolve the deep ambivalence and even opposition toward action in both parties, and Boehner's spokesman followed up the speaker's announcement by describing the resolution's passage as "an uphill battle." Dozens of conservative Republicans and several liberal Democrats have come out against intervention, and may be prepared to ignore the positions of their leaders and the president.
Pelosi stressed that Americans need to hear more of the intelligence to be convinced that a strike is necessary. "I'm hopeful that the American people are persuaded," she said.
"This is behavior outside the circle of civilized human behavior and we must respond," she argued as she left the West Wing.
Obama met with more than a dozen lawmakers in the White House Cabinet Room to press the case for strikes aimed at dismantling Assad's chemical weapons capabilities. The president said he's confident Congress will authorize the strike and tried to assure the public that involvement in Syria will be a "limited, proportional step."
"This is not Iraq, and this is not Afghanistan," Obama said.
Tennessee Republican Sen. Bob Corker, top Republican on the Foreign Relations Committee, told reporters Tuesday that he was working with panel Chairman Robert Menendez, D-N.J., to craft a resolution narrower than the broad measure the administration proposed on Saturday. He said their resolution, which could be ready as early as Tuesday evening, would limit the duration of the operation and prevent the deployment of U.S. ground troops.
Obama indicated he is open to changing the language to address lawmakers' concerns and called for a prompt vote.
"So long as we are accomplishing what needs to be accomplished, which is to send a clear message to Assad, to degrade his capabilities to use chemical weapons, not just now but also in the future, as long as the authorization allows us to do that, I'm confident that we're going to be able to come up with something that hits that mark," Obama said.
Sen. Rand Paul said he would probably vote against any resolution. But he said it also wouldn't be helpful to amend the resolution in a way that constrains the president too much to execute military action, if authorized.
After Obama met with the congressional leadership, administration officials offered a classified briefing for all members of Congress. Sen. Joe Manchin, D-W.Va., emerged saying he has concerns about a U.S. attack, including how Assad's purported use of chemical weapons represented a threat to the U.S. "There's an old saying, we don't have a dog in the fight. In this case, back home in west Virginia, they're saying we don't have any friends in the fight either," Manchin said.
Asked specifically about Boehner's endorsement, freshman Rep. Trey Radel, R-Fla., said he still hadn't made up his mind.
"Being new here, I'm very skeptical of Republicans and Democrats that have dragged us into wars of the past," he told reporters. "Still today, when we look at Afghanistan and Iraq, I am questioning: What is the end goal within these countries? What have we accomplished with so many lives being lost?"
Boehner spokesman Brendan Buck put responsibility for winning votes in the White House's hands in a written statement following up on the speaker's brief comment to reporters. "Everyone understands that it is an uphill battle to pass a resolution, and the speaker expects the White House to provide answers to members' questions and take the lead on any whipping effort. All votes authorizing the use of military force are conscience votes for members, and passage will require direct, continuous engagement from the White House," Buck said.
Secretary of State John Kerry, Defense Secretary Chuck Hagel and Joint Chiefs Chairman Gen. Martin Dempsey also attended the meeting with lawmakers before heading over to Capitol Hill for testimony later in the day before the Senate Foreign Relations Committee.
The U.S. said it has proof that the Assad regime is behind attacks that Washington claims killed at least 1,429 people, including more than 400 children. The Britain-based Syrian Observatory for Human Rights, which collects information from a network
