The interview was contentious at first, according to two people familiar with the matter, but investigators ultimately found his testimony credible and even surprising.

Christopher Steele, the former British spy behind the infamous “dossier” on President Donald Trump’s ties to Russia, was interviewed for 16 hours in June by the Justice Department’s internal watchdog, according to two people familiar with the matter.

The interview is part of an ongoing investigation that the Justice Department’s inspector general, Michael Horowitz, has been conducting for the past year. Specifically, Horowitz has been examining the FBI’s efforts to surveil a one-time Trump campaign adviser based in part on information from Steele, an ex-British MI6 agent who had worked with the bureau as a confidential source since 2010.

Horowitz’s team has been intensely focused on gauging Steele’s credibility as a source for the bureau. But Steele was initially reluctant to speak with the American investigators because of the potential impropriety of his involvement in an internal DOJ probe as a foreign national and retired British intelligence agent.
