Rep. Grimm: Changed Mind on Syria Because US Credibility Already Lost

Rep. Michael Grimm, R-N.Y., told CNN's Wolf Blitzer on Monday that he was solidly behind giving President Barack Obama authority to strike Syria.

Now, he's changed his mind, and told CNN on Thursday he doesn't think taking action will serve any purpose – and that Obama's indecisiveness has already irreparably hurt American credibility anyway.

Host Jessica Yellin played video of Grimm's forceful words on Monday when he supported backing Obama, and repeatedly asked him what had changed since then.

"I think, at this point, the world is looking at the indecisiveness, they're looking at how the president has bungled this, and now we can no longer get our credibility back," Grimm said.

He also told Yellin she should play more of his quote, rather than an edited version that focused on him repeatedly saying a strike against Syria was necessary because Obama had drawn a "red line" against using chemical weapons.

Grimm said Obama has failed to get allies to back an American attack.

"He's overseas doing that right now as we speak," Yellin interrupted. "He's working on getting a coalition. He's trying to build a coalition as we speak overseas, right now."

"And he appears to be failing, from the intelligence that I'm receiving," Grimm countered.

Asked if he had been pressured to change his mind, Grimm said no.

"This is totally my decision, something I've been thinking about, praying on, struggling with since we've heard about the use of chemical weapons," he said.
