There is commonly a gap, why I don't know. Perhaps wanting to take a second look at the info for accuracy.
If they are good journalists, they will check and double check and multiple check their sources, before running with it again. If they dare say it again on live TV, but still, here at nearly 7:00 p.m. Eastern, have nothing of it on their affiliated news websites in written form, as a flash or ticker or what not, something seriously is out of whack. I suspect they are not talking again or speculating the "Iranian Guards" side of this on CNN or Fox as of right now--but are quietly backtracking?
