Flynn burying the lede

This is by far the most interesting aspect of today's release.

They didn't write the 302 until Aug 22, 2017?

Strzok was removed from the team in Aug 2017.

Was this bogus 302 his final act BEFORE being removed?

Or was this 302 a 'redo' by the other agent to clear the record AFTER Strzok was removed?
