This bit of Senatorial theater is making the rounds now:

Returning to the Senate after his securing the Democratic presidential nomination, Obama and Lieberman greeted each on the Senate floor in the Well as they were voting on the budget resolution.

They shook hands. But Obama didn’t let go, leading Lieberman – cordially – by the hand across the room into a corner on the Democratic side, where Democratic sources tell ABC News he delivered some tough words for the junior senator from Connecticut, who had just minutes before hammered Obama’s speech before the pro-Israel group AIPAC in a conference call arranged by the McCain campaign.

The two spoke intensely for approximately five minutes, with no one able to hear their conversation. Reporters watched as Obama leaned closely in to Lieberman, whose back was literally up against the wall.

(emphasis mine)

A source said that it was, “a cordial and friendly discussion”, but I’m inclined to think that that depends on how you define those words, and this sounds just like how LBJ used to work people.

If it’s true, I’m favorably impressed.
