I’m only following on Twitter, but it looks like Robert Gibbs has stepped in it while answering a question on Dick Cheney’s weekend criticisms of President Obama:

Jake Tapper tweets:

Gibbs reax 2 Cheney criticisms:”I guess Rush Limbaugh was busy so they trotted out the next most popular member of the Republican cabal.”

And Chris Cillizza:

Gibbs MUCH more measured on Cheney…recognizing he got out over his ski tips earlier on it
Here’s the reality…no matter what Gibbs says from this point onward in briefing the Cheney comments are the lead…”cabal” will haunt him.
Chip Reid calls Gibbs on sarcastic response on Cheney…Gibbs says he was dead serious…GOP “cabal” may have been a bit strong.
