Consultants affiliated with a small Washington, D.C., firm called Beacon Global Strategies hold the unique privilege of providing high-profile foreign policy guidance to Hillary Clinton, Marco Rubio, and Ted Cruz, among others.

The bipartisan firm was founded in 2013 by former senior officials from the State Department, Department of Defense, and Central Intelligence Agency, and quickly had more than a dozen clients, primarily defense contractors, according to Defense News.

Philippe Reines and Andrew Shapiro, both considered part of Clinton’s inner circle of foreign policy advisers, are founders of the firm. Reines served as a longtime spokesperson for Clinton and Shapiro served as her assistant secretary of state for military affairs.
