From a live MSNBC interview (because if it had been pre-recorded, the Obama huggers over at MSNBC would have not allowed this to air):

"I love Obama, and you'll never find a truer Democrat than me, but this whole idea of any president of the United States drawing lines saying that if any country does something, that he considers wrong, that the nation is going to war, it's unheard of–drawing a red line. So, of course, it's embarrassing. I wish it didn't happen,"

Kerry too:

"I guess Secretary Kerry is even more embarrassed than me after making his emotional speech about this was urgent. And clearly, as I said earlier, I couldn't see anything urgent about it, and I'm glad the president reviewed his thinking and he is going to give us time to discuss it."
