Max Boot says: "We don’t know what Mueller has learned. But we can look at the key, publicly available evidence that both supports and undercuts this explosive allegation. This is hardly a “beyond a reasonable doubt” case that Trump is a Russian agent — certainly not in the way that Robert Hanssen or Aldrich Ames were. But it is a strong, circumstantial case that Trump is, as former acting CIA director Michael Morell and former CIA director Michael V. Hayden warned during the 2016 campaign, “an unwitting agent of the Russian federation” (Morell) or a “useful fool” who is “manipulated by Moscow” (Hayden). If Trump isn’t actually a Russian agent, he is doing a pretty good imitation of one."
