Among the bombshell revelations is an admission by Steele that he violated his confidential human source agreement with the FBI and leaked information from his dossier to the news media in the final weeks of the election because he wanted to counteract new revelations in the Hillary Clinton email scandal that were hurting her election efforts. The former foreign intelligence officer made the confession in a fall 2017 interview with agents.

Steele told the bureau that then-FBI Director James Comey's decision to reopen the Clinton email probe in fall 2016 triggered him to leak his dossier details in what he described as a taking-the-gloves-off moment.

The FBI interview summary makes clear that Steele, a British citizen, was allegiant to Clinton, did not like Trump and believed a Trump presidency would be negative for his homeland and thus made a decision to meddle in the U.S. election by leaking information to the news media.
The leaks, which led to Steele's termination as an FBI informant, have been known for more than a year, but his motivation for leaking was hidden in the classified documents
