Former British spy Christopher Steele admitted that he relied on an unverified report on a CNN website for part of the “Trump dossier,” which was used as a basis for the FBI’s investigation into Trump.

According to deposition transcripts released this week, Steele said last year he used a 2009 report he found on CNN’s iReport website and said he wasn’t aware that submissions to that site are posted by members of the public and are not checked for accuracy.
