"a person familiar" --that's the source?
The rest of that Politico article discounts the Feb 16th date saying "as soon as the 16th" implying the 16th might be the earliest that Russia will be ready. And says "It's possible the Feb. 16 piece of intelligence is raw and not the overall assessment of the United States".
I think that's what Steve Lookner was saying. Biden never said it would happen on the 16th, at least not publicly. Unnamed "sources" or "a person familiar" might have heard it, but we don't really know.
And since it contrasts with Biden's and his administration's public comments, the public comments are to be believed, not "a person familiar".
Biden has plenty of incompetency to account for without having to defend "intel" that they didn't publish and that contrasts with their public statements.
Just as coincidence, Tucker literally just now, FOX had a segment on this topic.
He showed a montage of MSM recorded news clips of the last week or two where they were clearly saying Biden administration officials were warning the Russian invasion of the Ukraine would start on Wednesday the 16th. CNN, MSNBC and several others I can’t recall.
True in none of them Biden was shown saying it but again they all said they were notified by “administration officials”. So he must be involved. Well at least his handlers are.
I imagine one could find it somewhere.
