In a memo to staff, the editor-in-chief of Bloomberg News told the newsroom that the publication will continue its “tradition of not investigating” its CEO and namesake, Michael Bloomberg, or his family and foundations after he declared his candidacy for president on Sunday.

The head of Bloomberg News, John Micklethwait, said the policy not to investigate will be extended to other candidates in the Democratic primary.

The union representing journalists at the Bloomberg industry publication group on Monday condemned the company's decision to bar journalists across the broader Bloomberg organization from investigating Democratic candidates for president.

In a statement released on Twitter, the guild, which represents Bloomberg Law, Bloomberg Tax, Bloomberg Government and Bloomberg Environment called the company's decision an effort to "silence" the company's reporters.

Back when he was New York’s mayor, Mike Bloomberg routinely feuded with the press over his whereabouts.

He doggedly refused to release his weekend schedule, even if he was traveling out of town, favoring his own privacy over the public’s right to know.

Now, as of Sunday, he’s running for president. But one organization that won’t be covering him aggressively is Bloomberg News.
