Maybe interesting that Trump uses Twitter for IPhone most of the time but on occasion uses Twitter Web Client. Either way his location is never revealed and neither is his IP. I use the direct Twitter API to get all info available in JSON format. https:// pastebin.com/vR2SukEC
Some samplings of the Web Client tweets are:

There are more in the pastebin. Also if you scroll down to the time of his Asia trip, most of his tweets were from the Web Client instead of his IPhone. His only use of IPhone was probably onboard AF1. That's smart.
