Other good speakers as well (Pompeo, DeSantis, Noem). It might be worth hearing what POTUS and the others have to say. I don’t know who will be broadcasting it as yet, will update in comments if I find out. Just an FYI (and apologies if this has already been posted. Without a search function duplicates are inevitable).

See comment of sparty_girl, above. I haven’t been able to find any time or any broadcast outlet so I’m hoping Pompeo and/or others will at least give a synopsis of what POTUS spoke about. Look at the article link in my comment (vs the post), above, for some info on Trump-RNC relationship.
