RT Kai Trump (@kaitrump)I had an amazing time filming with my Grandpa to kick off my new series called 1 on 1 with Kai. In the video, everyone gets to see the bond we have, especially on the golf course. This is my favorite video I have filmed so far and holds a lot of meaning to me. I hope you enjoy this very special video. Out now on YouTube!https://t.co/uufCTwbO74 ...
