McCain says signing letter may have been a mistake.

Gosh, maybe not. But why would almost all of the Republicans in the Senate do such a thing?

“It’s also symptomatic between the total lack of trust that exists now between we Republicans and the president,” he said. “This has established a poisoned environment here which sometimes causes us to react maybe in not the most effective fashion.”

Isn't it a shame that there's such a lack of trust just mysteriously existing, when all Republicans ever did was say that they were going to block everything President Obama tried to gain partisan points and make it easier to defeat him in 2012. Republicans are so very sad that after years of them refusing to work with the president, he stopped bending over backward to try to do so. Now, Republicans are left with no choice but to retaliate by breaking all precedent in writing to Iran to try to scuttle a diplomatic solution to nuclear concerns.
