Rep. Grimm: No one pressured me to flip Syria position

Grimm’s comments are consistent with the stated positions of Republican and Democratic leaders, who have said they will largely avoid whipping votes for a resolution.

Speaker John Boehner (R-Ohio) and Majority Leader Eric Cantor (R-Va.) are two of the few House Republicans who have publically backed the president. They have said it will be the administration’s responsibility to bring members over to its side.

According to The Hill’s count, 75 Republicans are opposed to or leaning against the measure. Without Grimm, only 10 Republicans have vocalized support for it.

Grimm said a large factor in his change of heart was Obama’s comments that the international community — not Obama alone — established the “red line” against the use of chemical weapons by the Syrian regime.

“When I see the president backtracking on what he said and what I was relying on to back him, that obviously is a big concern with me,” he said. “The other things is in the last 72 hours, none of our allies have stepped up.”

In earlier statements of support, Grimm said it was essential to back up the president’s words with action in order to maintain U.S. credibility. But he alleged Thursday that the United State’s already looks indecisive and weak. 

“I don’t think we can get that back now,” he said.
