I get on reddit as well and there are a lot of articles about trump's health, some are saying that he's had ministrokes, and that the perception of his health is looking worse. The announcement coming in a few hours is thought to have something to do with this.
1. Speculation on ministrokes https://wegotthiscovered.com/politics/concern-mounts-over-trump-health-as-evidence-hes-suffering-series-of-mini-strokes-emerges/
2. Article speculates on the content of the upcoming announcement and concludes that it could have something to do with his health https://www.dailystar.co.uk/news/us-news/donald-trump-make-mystery-announcement-35830731
3. Trump has been recycling old photos and has stayed out of the camera for 2 or 3 days now. This is unusual and naturally people are thinking that something is very wrong with trump. https://www.irishstar.com/news/politics/trump-hides-cameras-second-day-35824075
