"Under what circumstances a fabulously wealthy Putin-allied Russian billionaire might "need private briefings" about the state of an American presidential race, as detailed to him by none other than the campaign chairman of the Republican presidential candidate, is unclear. Very unclear. Manafort's spokesman claims the effort was because the Russian owed Manafort for past work. Again, though, how being owed money by a Russian businessman might translate into the Russian businessman getting "private briefings" on the state of the presidential campaign Paul Manafort was running is unexplained."
