As the former White House press secretary, Scott McClellan, promotes his tell-all book on the Bush administration, Mayor Bloomberg says that such exposes are nothing to be admired.

“I have always thought that when you work for somebody you have an obligation to not write a tell-all book afterwards,” Mr. Bloomberg told reporters today. The owner of a multi-billion dollar corporation, Bloomberg LP, he added that his opinion held true “whether you’re in an administration or whether you work for a private company.”

Mr. Bloomberg said that memoirs should be distinguished from exposing wrongdoing due to their timing.

“If you think the organization you work for is breaking the law, there are whistleblower protections and you should avail yourself of the opportunity to set things right while you’re there,” he said.

Mr. Bloomberg said that he did not believe that Bloomberg LP required employees to sign waivers preventing the release of books like Mr. McClellan’s.

“I don’t believe we ask anything; I just hope we hire people who are a little more responsible,” he said.
