I’m hoping that the first question from PDJT’s legal team to Cohen is - “Mr. Cohen - are you a liar?”.
That would qualify as a “boom” moment.
The only sound response from Cohen is: “I have never lied under oath.”
If that is true.
That or very similar will be asked. He'll be ready with some tale of woe about how he learned to lie during his tenure with Trump, who was and is the master ... he had a family to feed and he was frightened ... blah, blah blah.
