I found a neat little resource while doing a dig on trying to find exactly where POTUS was during Vegas shooting. This is a site that collects all presidential press pool releases. Pretty handy and is a good pulse on Trump news and moves. These come from the people that follow him around on planes and stuff so I'm sure a lot of good details can be gleaned. If they overhear calls they write it down, lots of good stuff. I'm sure a lot can be inferred from schedules, visits, meetings, et cetera.
