Hillary Clinton’s campaign released a letter this week in which 10 foreign policy experts criticized her opponent Bernie Sanders’ call for closer engagement with Iran and said Sanders had “not thought through these crucial national security issues that can have profound consequences for our security.”

The missive from the Clinton campaign was covered widely in the press, but what wasn’t disclosed in the coverage is that fully half of the former State Department officials and ambassadors who signed the letter, and who are now backing Clinton, are now enmeshed in the military contracting establishment, which has benefited tremendously from escalating violence around the world, particularly in the Middle East.

Here are some of the letter signatories’ current employment positions that were not disclosed in the reporting of the letter:

Former Assistant Defense Secretary Derek Chollet, former Pentagon and CIA Chief of Staff Jeremy Bash, and former Deputy National Security Adviser Julianne Smith are now employed by the consulting firm Beacon Global Strategies, a firm we profiled last year. Beacon Global Strategies’ staff advises both Clinton and Republican candidates for president, including Ted Cruz and Marco Rubio. The firm makes money by providing advice to a clientele that is primarily military contractors. Beacon Global Strategies, however, has refused to disclose the identity of its clients.

Former Undersecretary of State Nicholas Burns is a senior counselor at the Cohen Group, a consulting firm founded by former Defense Secretary William Cohen. The firm “assists aerospace and defense firms on policy, business development, and transactions,” including deals in the U.S., Turkey, Israel, and the Middle East.

Former Undersecretary of Defense Jim Miller is an advisory board member to Endgame Systems, a start-up that has been called the “Blackwater of Hacking.” Miller is also on the board of BEI Precision Systems & Space, a military contractor.
