Late last month Boston.com noted that Brett O'Donnell, who served as Mitt Romney's debate coach in the primaries, was no longer with the campaign:
In February, after well-received debates preceding Romney’s primary victory in Florida, the campaign told new debate coach Brett O’Donnell that his services were no longer required. O’Donnell had been widely praised in the media for Romney’s improved performances.
On Fox News tonight, O'Donnell explained what he thought Romney needed to do in tomorrow's presidential debate. He was also asked why he was no longer coaching the candidate.
"I think the governor's got a great team and we'll just leave it at that," he said.
