The finding is expected to be part of Justice Department Inspector General Michael Horowitz's review of the FBI's effort to obtain warrants under the Foreign Intelligence Surveillance Act on Carter Page, a former Trump campaign aide. .....Some witnesses who have been interviewed in Horowitz's investigation have said they expect the inspector general to find mistakes in the FBI's handling of the FISA process, but that those mistakes do not undermine the premise for the FBI's investigation. Based on previous reports from Horowitz, I would expect nothing more than the above.
