While in Afghanistan, one of the things we had to do was a weekly briefing to our level general about the status of our areas. We'd list four or five things that were of "general officer" interest. S1 would do their bit; then S2; then S3; etc. If there were no changes, we'd put "NTR" (nothing to report). Sometimes a general would notice that "NTR" had been up there for an item two or more weeks in a row; so then he/she would ask if it needed to continue being on the weekly report.
Half the time, I was merely keeping in items that my predecessor(s) had provided, without any explanation as to why they were there in the first place ("we were told to put items on a slide, so we did"); and if I was ever asked if something needed to continue being on the weekly report, I usually said something along the lines of "I don't know why it was there in the first place." In fact, I seriously got in trouble with my immediate supervisor (an Air Force colonel) over this. He had us do a bi-weekly briefing for him; it was 24 slides, and he would typically make it last 3.5 hours or more, and we never got past slide 12. My guys had been in country a couple of weeks longer than me; I started asking them, "what's this slide about?" If they told me they didn't know, and that their predecessor hadn't explained the slide to them, and there were no notes anywhere about the slide, I'd hide it. I got the slide deck down to 12 slides this way, and the colonel didn't notice for the next two briefings (one month). Then one night, me and one of the guys were in talking to him about something else, and someone called him about the status of a TOC. He mentioned that he had the answer at his fingertips, because it was in the slide deck; I grimaced and said, "no, no you don't, because you hadn't noticed that we deleted that slide from your deck." So then he and I had a discussion--well, he discussed, and I said "yes sir" every so often--about deleting slides without telling him....
Sorry, but I'm seeing this as a "we've always done it that way" item; and Trump isn't planning on doing it that way any more.
