So we know from DNI Grenell's release of documents names Biden as a recipient of Flynn's unmasking https://www.foxnews.com/politics/read-documents-listing-names-of-obama-era-officials-who-sought-to-unmask-michael-flynn

In further documents, Sally Yates specified she learned of Flynn through Obama. However, the way Obama talked, it sounds like he knows the information he got was retrieved through Ill-gotten-means.

Quote (Sally Yates): “Obama specified he did not want any additional information on the matter but was seeking information on whether the White House should be treating Flynn any differently.”

I would assume Obama got the information from Biden. This means Biden is far deeper in this mess. And with talk that this spying happened to ALL candidates.. Yeah he knows he's fucked. Add in his Son's China and Ukrain money thanks to Biden.. He seems like the really bad dude who just couldn't keep it in his pants and went overboard.

So that leads to my followup conjecture.. Is he faking the Dementia as a defense for the upcoming trials?

This by no means exonerates Obama, he after all has worked hard to cover it up.
