The other thing that is very curious is the timing of when Roberts invited Obama for the meeting - an unprecedented event that had never been done for ANY POTUS before taking office, much less one with lawsuits coming before SCOTUS, and even much much less the invitation coming from the chief justice who knew there would be cases before SCOTUS at the time the meeting took place.
IOW, Roberts in an unprecedented move specifically invited Obama for what Roberts knew would be an unethical ex parte communication.
And he did it on the exact same day as the first eligibility case came before SCOTUS. The day on which Roberts knew what the court had decided but the public hadn’t yet been notified. Roberts made sure not only that he invited Obama, but that the public got the news of the invitation before they knew what SCOTUS had decided on the Donofrio case. If I didn’t know better (cough), I’d almost say that was a deliberate attempt to make the invitation look as fishy as possible to as many people as possible. On the first day that SCOTUS actually had to decide something about Obama’s eligibility.
This was after the whole big mess with SCOTUS clerk Danny Bickel, where lots of people like myself wrote to SCOTUS to tell them there was funny business going on. Roberts probably knew there were already red flags raised by others and it sure looks to me that he made sure to raise some of his own in answer to those already raised.
