But Rybolevlev's movements have actually been discussed for months. 

Computer scientist John Mashey wrote in February that the oligarch's airplane "made at least 7 visits to New York City … spending several days or more on each visit, usually overlapping with Trump presence there, given his habit of flying back most nights during the campaign."

Remember that the oligarchs are a state-sponsored network of criminals," Johnston said. "They are totally dependent to stay alive on being in the good graces of Vladimir Putin. 

And when he wants things done, they do them."

"In the case of Rybolevlev, he turned over $25o million, quote-unquote "voluntarily," in a dispute with Putin, where Putin was essentially bringing him to heel."
