Former British MI6 agent Christopher Steele spoke with investigators on special counsel Robert Mueller’s team for two days, the Telegraph reports.
Steele, who compiled the dossier alleging ties between Donald Trump and Vladimir Putin, spoke with investigators behind closed doors as Mueller’s team tried to ascertain the veracity of those claims.
The dossier sits at the center of a public battle over the Russia investigation. Republicans have claimed the Steele dossier was used by the FBI to obtain a Foreign Intelligence Surveillance Act warrant on onetime Trump aide Carter Page. In fact, the FBI knew of Page’s ties to Moscow as early as 2014.
