The doubts highlighted in the e-mails left a cloud over the E.I.A., which policymakers rely on for information. ![]() The Times redacted all the names, substantial sections of the e-mails and even whole e-mails. The e-mails, quoted extensively in the article and published in a document “viewer” on, captured conversations between summer 2009 and April 2011.
