President Obama called Speaker John Boehner (R-Ohio) on Thursday to discuss the status of deliberations over Syria, one day after the top House Republican demanded Obama “make the case” for military action in response to an alleged chemical weapons attack.

“During the call, the Speaker sought answers to concerns outlined in his letter to the president yesterday, including the legal justification for any military strike, the policy and precedent such a response would set, and the objectives and strategy for any potential action,” Boehner spokesman Brendan Buck said.

“Only the president can answer these questions, and it is clear that further dialogue and consultation with Congress, as well as communication with the American public, will be needed.”
