All About the Envelopes
After examining the video of Bush's Funeral, it's apparent that the programs that contained the envelopes were distributed AT RANDOM (or were not targeted). It would not have been possible to insure that Michael Obama received his specific envelope.
Evidence:
The following YT vid is the master that contains the angle that picks up MO finding the envelope. About 30 seconds earlier in the same video, we see MO picking up the programs. She picks up TWO, and hands the top program to FLOTUS, and keeps the second for herself:

Michael's action (picking up the programs and offering one to FLOTUS) is RANDOM/unpredictable. Barry could just has easily have picked up the top one, and given DJT the bottom one containing the envelope.
-OR-
Everyone received envelopes in their programs with a uniform message, and the Trumps just ignored the envelopes.
Another YT vid shows only Michael's interaction clipped from the entire 2:58 funeral video:

Perhaps "Our promise to 'counter'." means something else?
