Assuming that there is no serious detriment to national security I think it might be better to release it all. Once it’s released there will be little reason to hold back the actual evidence. Most of the info will already be in the public domain.
I heard an expert argue that more damage to the country will be done by withholding this memo than would be done if the classified information were released.
Admittedly arguing from a position of ignorance on my part, I agree with him.
I agree.
Probably some valid reason to remove some of the data - other than that, Trump is playing them and suing the extra time to ensure he can slap them upside the head once again by peeing on their memo parade....
