Among other matters, the IG's report is expected to determine "whether there was sufficient justification under existing guidelines for the FBI to have started an investigation in the first place." Critics of the Trump-collusion probe believe that there was never probable cause that a crime had been committed, therefore, there was no legal basis for launching the investigation. The findings of the Mueller report– that there was no cooperation or collusion between the Kremlin and the Trump campaign– seem to underscore this broader point and suggest that the fictitious Trump-Russia connection was merely a pretext for spying on the campaign of a Beltway outsider whose political views clashed with those of the foreign policy establishment.
