Mayor Scott Smith of Mesa, Ariz., declined to say exactly what he heard Obama and Brewer talk about during their now-infamous tiff next to Air Force One.

But the mayor said he was standing right next to the governor when the exchange took place and Obama didn’t seem to be in any kind of hurry to leave.

“There was no sense that he was running to or from anything,” Smith told TPM. In fact, he said, the president stayed and had a pleasant conversation with Smith, who’s a Republican, and Phoenix Mayor Greg Stanton, a Democrat.

It was “just the four of us,” Smith said. “Mayor Stanton and I had a decent talk with him.”

The mid-sentence storming away is kind of the crux of the aggrievement Gov. Brewer’s been selling in a an impressive number of media appearances:

“I thought he was kind of thin-skinned,” she said, adding that Obama walked away while she was “in the middle of a sentence.”

Asked whether she regarded that as disrespectful, she replied: “Well, I would never have walked away from anybody having a conversation. And, of course, that is what it is. It is disrespectful for me.”
