On July 17, 2008, The Trump Organization purchases the website domain names TrumpRussia.com and TrumpTowerMoscow.com.
There’s nothing really conspiratorial about this. We know that Trump is involved with Putin and that people close to him have been in talks for Trump Tower Moscow. The conversations started at least two years ago, around the time that Ivanka Trump sat in Vladimir Putin’s chair. The websites were probably purchased for potential Trump projects in Russia.
DTTM Operations LLC becomes the new owner of both websites in October 2020. It’s a Delaware company, so it doesn’t have to disclose its owners, but it’s not a mystery.

DTTM stands for Donald Trump Trademarks. At the time of this writing, the company is also listed as the trademark holder for all Trump brands and the domain name owner for other Trump sites, including DonaldJTrump.com.
Why does Trump still own the domain names 13 years later?
