Adelsons give $15M more to McConnell super PAC

Published 9:50 a.m. ET Dec. 15, 2016 | Updated 10:03 a.m. ET Dec. 15, 2016

Casino magnate Sheldon Adelson and his wife Miriam gave another $15 million late in the fall campaign to Sen. Mitch McConnell’s super PAC devoted to electing Republicans to the U.S. Senate.

That brought the Adelsons' total contributions to Senate Leadership Fund to $35 million – dwarfing even other billionaire donors who have given seven-figure amounts to the political causes of McConnell over the last eight years.

Here's a source of his money

Mitch enters the story through his brother-in-law, Jim Breyer, a global tech venture capitalist. Mitch is married to Secretary of Transportation Elaine Chao, and Jim’s married to her sister, Angela, CEO of the family’s shipping enterprise.

The story seems to begin in 2005 when Jim invested in Facebook and joined their board. At an international tech summit in 2009 he met Kremlin backed Yuri Milner, a Russian tech entrepreneur, along with Saudi Crown Prince Mohammed bin-Salman (MBS).

Milner and Breyer began working together through Milner’s company, DST, and then circuitously, Milner bought stock and later a board seat at Facebook and Twitter. Consequently, Russia owns 8% of Facebook and 5% of Twitter with Putin’s agent on those social media boards.
