“Not me,” said an exasperated-looking senior adviser, when asked who was responsible for Mr. Eastwood’s speech. In late-night interviews, aides variously called the speech “strange” and “weird.” One described it as “theater of the absurd.”…

A senior Republican involved in convention planning said that Mr. Eastwood’s appearance was cleared by at least two of Mr. Romney’s top advisers, Russ Schriefer and Stuart Stevens. This person said that there had been no rehearsal, to the surprise of the rest of the campaign team.

But another adviser said that several top aides had reviewed talking points given to Mr. Eastwood, which the campaign had discussed with the actor as recently as a few hours before his appearance. Mr. Eastwood, however, delivered those points in a theatrical, and at times crass, way that caught Romney aides off guard, this person said.
