I think this is just another misinformation. They discussed it on FOX two days ago. No one knows if or when his Security clearance was revoked. Good disinformation as it pisses people off.
No one publicly knows. And for sure and certain, the NYT is a cesspit of stinking lies.
One of the Fake News main tactics is to make Trump look weak and ineffectual to his supporters, and this supporter is not buying their excrement labeled “news”!
