Miller engaged in irresponsible conspiracy-theory mongering.
But he is not responsible for disclosing the intel that we have a spy in Putin’s inner circle. That was contained in this NYT article, and Miller said he was disturbed that someone in the US intel community apparently leaked that info to the NYT.
When someone at his level confirms a press story - he just compromised the operation
Clearly, Trump didn't leak it to the NYT, so where would any such leak come from? At this point, how can anyone believe anything that comes out of the previous administration? Obama’s administration weaponized government in their attempt to hardwire irreversible ‘transformation of the US’. All the while, Obama continued his ‘I'm so thoughtful, principled, and reasonable’ charade for the all too willing media and his various sycophants.
