Former CIA Director John Brennan and former FBI Director James Comey are under criminal investigation for potential wrongdoing related to the Trump–Russia probe, including allegedly making false statements to Congress. CIA Director John Ratcliffe referred evidence of wrongdoing by Brennan to FBI Director Kash Patel for potential prosecution, leading to the opening of a criminal investigation into Brennan. Similarly, an investigation into Comey is underway, but specific details are not disclosed. The investigations stem from the rushed creation of the 2017 Intelligence Community Assessment and the inclusion of the discredited Steele Dossier, with officials acknowledging politicization of the process by Obama-era appointees. The White House seeks accountability for the role of Obama-era intelligence officials in the Russia probe.
