"Does anyone know if Trump's election campaign allegedly received donations from the Russian government & can prove it?"
Well, the Rachel Maddows piece linked way above shows DJT himself received $60 million in 2008 (or thereabouts), just when he needed money. He'd bought a mansion for $40 million and it had sat empty for two years. Then someone paid him $100 million for it (and it sat empty again).
The "someone" was Russian billionaire Dmitry Rybolovlev, who is a major shareholder in the Bank in Cyprus, whose other major shareholder, Wilbur Ross is an American who, oh, has just been made US Commerce Secretary.
Of course that's not proving 45's campaign received money, it's just an example of how money can be funnelled to someone.
