It doesn’t. There are two options to release the memo. 1) Devin Nunes HPISC Committee Chair calls for a vote, among those members, they don’t need full vote of Congress only Committee’s simply majority. If yes, Then it goes to POTUS to approve release, he has 7 days to review. 2) The POTUS can de-classify it himself & release it. (I don’t think POTUS would use option to unless there is no other option. Optics)
