I think he knew, too. Having Rogers come to TT and, purportedly, "Tell him", wouldn't have blown Trump's cover as a naïve outsider, nor would it have burnt his moles.
I figure Brennan and Clapper were running the op from the Obama/Clinton side, and, going by the famous SM post back then, by a former/anonymous IC guy, saying Brennan was considered to have the operational capacity of an earthworm, Trump was inside their OODA Loop and wanted to keep it that way.
Just another angle to consider.
