Good analysis. Katrina had Wolfie on the ropes when she asked him exactly what Trump should apologize for.
She was technically incorrect with the comment about the rules of engagement, as Capt Khan died in 2004, way before Obama became Prez and changed the ROE.
The relentless way Wolfie kept coming back to the demand for an apology shows that CNN had an agenda and Wolfie was following orders.
If they can get a concession from the Trump camp at any level, they will beat Trump over the head with it.
DO NOT APOLOGIZE.
That was an illuminating exchange. Katrina answered his question, and he did not understand her answer! He's a dunce. She repeated it twice more, slowly, and he still didn't get it. Trump surrogates should try to figure out how to get under his skin. I think he would be very easy to rattle.
