I’m pretty sure he can’t use Executive Privilege because he was not president at the time of birth. The way I read the Executive Order, there is no mention that if the Court orders the documents he doesn’t have to comply. They can fle appeals if they want. The appeals can be denied or thrown out. Please don’t rain on my parade. :-)
If I remember correctly (or maybe not) a judge ordered Nixon to turn over tapes, and when they got them there was 18 minutes missing and I think that started the process to impreach him...but he quit....
