What an overreach-if this recording is even real-and/or unaltered-It hardly sounds like “secret documents” he had-more like just making an example of what he could do-and for that matter, the piece of paper he is using to illustrate could just be someone’s recipe for biscuits...
That recording they called “damning evidence” was made in the context of Gen. Milley PUBLICLY telling everyone that he was responsible for PREVENTING Trump from invading Iran ( implying that Trump wanted us to get into a shooting war without going through Congress). That was Trump’s attempt to correct Milley’s lies.
Trump was in fact, trying to avoid a war with Iran despite the advise of the Hawks in his team telling him to.
