Texas businessman Terry Giles, Ben Carson's former campaign chairman and close friend of more than 20 years, has been “shut out” from his presidential campaign just as the retired former neurosurgeon has ascended to the level of Republican front-runner.
Giles, who was one of the dominant forces behind Carson's exploratory committee back in early 2015, is no longer formally connected to the campaign nor is he acting as an adviser, sources close to the Carson's campaign told Bloomberg.
