The Center for Public Integrity has created a blog to list officials in public and private institutions who refuse to comment to reporters.

CPI"Lately – whether it's an investigative, nonprofit newsroom like us, an international outlet like the New York Times, or newer media like Politico or Buzzfeed – when journalists call, officials are choosing to comment less for stories on the record," CPI wrote in introducing the new Tumblr blog, "Couldn't Be Reached," published by CPI media relations specialist William Gray and engagement editor Sarah Whitmire.

CPI said the blog will focus on "institutions and people in power – both private and public" who decline to comment for stories in the public interest.

The first entries call out Senate candidate Alison Lundergan Grimes, the American Petroleum Institute, Centers for Medicare and Medicaid Services, and Circuit Court of Appeals Judge Edith Jones, among others.
