From the story here:
WASHINGTON — Within hours of opening an investigation into the Trump campaign’s ties to Russia in the summer of 2016, the F.B.I. dispatched a pair of agents to London on a mission so secretive that all but a handful of officials were kept in the dark. ...
Not only did agents in that case fall back to their typical policy of silence, but interviews with a dozen current and former government officials and a review of documents show that the F.B.I. was even more circumspect in that case than has been previously known. Many of the officials spoke on condition of anonymity because they were not authorized to discuss the investigation publicly.
But those who saw the investigation up close, and many of those who have reviewed case files in the past year, say that far from gunning for Mr. Trump, the F.B.I. could actually have done more in the final months of 2016 to scrutinize his campaign’s Russia ties. ...
Mr. Comey, after all, broke with policy and twice publicly discussed the Clinton investigation. Yet he refused repeated requests to discuss the Trump investigation.
