I think the 'antennae' was actually the control booth asking through his earpiece to get Graham to verify. Control booth operator was acting on instinct at first but then thought better or was overridden at which point Kilmeade was just told to get back on topic. There's likely still back room discussion at Fox over whether it's the right time for this. Judge Napolitano already got into trouble there over the same issue remember.
“...control booth asking through his earpiece to get Graham to verify.”
Maybe, but Killmeade is one of the fastest on his feet at Fox. The topics and key points are always agreed to beforehand by some lowly producer, DACA, Mueller/Dossier and the Pharm Co. that is spreading the wealth thanks to Trump’s tax plan.
LG went too long on his Amnesty pet project so had to be prompted by Killmeade on the dossier “recent discoveries”. The take away here is that LG is talking about the fraudulent use of the dossier to get a warrant as a forgone conclusion without specifically saying it was. Clever.
