After his name surfaced in news media reports related to probes by House Republicans into the dossier, Winer authored a
Washington Post oped in which he conceded that while he was working at the State Department he exchanged documents and information with dossier author and former British spy Christopher Steele.
Winer further acknowledged that while at the State Department, he shared anti-Trump material with Steele passed to him by longtime Clinton confidant Sidney Blumenthal, whom Winer described as an “old friend.” Winer wrote that the material from Blumenthal – which Winer in turn gave to Steele – originated with Cody Shearer, who is a controversial figure long tied to various Clinton scandals.
