Agents bolstered the dossier by citing the Fusion-inspired Yahoo News story on Trump aide Carter Page that was actually not a second source, but was based on the same dossier. Mr. Steele lied to the FBI by saying he had not spoken to Yahoo News, when in fact he had, the Senate report said.
The FBI planned to pay Mr. Steele to continue investigating Mr. Trump. But the bureau suspended him in late October when he went to Mother Jones magazine and disclosed the collusion investigation.
Yet, the FBI continued to cite the Yahoo News story as corroboration in three subsequent wiretap renewals, the Senate report said.
