It remains unclear, however, whether the House will hold a vote on the Senate resolution or craft a version of its own.
Rep. Ileana Ros-Lehtinen (R-Fla.), the former chairwoman of the House Foreign Affairs Committee, on Wednesday told Secretary of State John Kerry there was a “rumor circulating” that the House might not vote on a Syria resolution at all.
A handful of House GOP staffers surmised that Ros-Lehtinen was "speculating" that a resolution would have to come up on the floor for consideration should Foreign Affairs Committee Chairman Ed Royce (R-Calif.) fail to have enough support on his committee to recommend that the full House approve the authorization.
The Hill’s Whip List shows there is a significant and growing bloc of opposition in the House to approving military force.
Though House Speaker John Boehner (R-Ohio) endorsed military action on Tuesday, he said it was incumbent on the president to secure enough votes for passage.
Many lawmakers say they have received a flood of calls from constituents who are opposed to U.S. action in Syria.
