Special counsel Robert Mueller’s investigation is looking at “suspicious financial activity” involving “Russian operatives.” Bloomberg’s Timothy L. O’Brien reports that the other shoe to drop may involve “a troubling history of Trump’s dealings with Russians exists outside of Russia: in a dormant real-estate development firm, the Bayrock Group, which once operated just two floors beneath the president’s own office in Trump Tower.” O’Brien writes that “one of Bayrock’s principals was a career criminal named Felix Sater who had ties to Russian and American organized crime groups. Before linking up with the company and with Trump, he had worked as a mob informant for the US government, fled to Moscow to avoid criminal charges while boasting of his KGB and Kremlin contacts there, and had gone to prison for slashing apart another man’s face with a broken cocktail glass.” Lots of other shady details at the link.
