“He needs to take a valium before he comes in and talks to Republicans..."
I know the feeling - sometimes I need a good belt myself before listening to El Rushbo, which can be awkward if I am tuning in on the car radio.
A bit more context makes it appear that Roberts thinks Obama was channeling his inner Paul Krugman:
"The more he talked, the more he got upset," Sen. Pat Roberts (R-Kan.) said. “He needs to take a valium before he comes in and talks to Republicans and just calm down, and don’t take anything so seriously. If you disagree with someone, it doesn’t mean you’re attacking their motives — and he takes it that way and tends then to lecture and then gets upset.”
