The Mercers part own Breitbart.
The Mercers financed Trump's campaign bigly.
The Mercers, like Sheldon Adelson, love John Bolton (which explains why Trump has considered Bolton for both Secretary of State and National Security Advisor).
Robert Mercer is a billionaire hedge fund manager and hates the recent legislation imposed on Wall Sreet, and his daughter, Rebekah, is married to Sylvain Mirochnikoff who is a managing director of Morgan Stanley (so this explains why Trump is eager to unleash Wall Street).
Breitbart News CEO Larry Solov confirmed Friday that the Mercer family – GOP mega-donors and key backers of President Trump's campaign – are part owners of the right-wing news site, according to multiple reports.
