Justin Elliot reports: A top executive at Lockheed Martin recently worked with lobbyists for Bahrain to place an Op-Ed defending the nation’s embattled regime in the Washington Times — but the newspaper did not reveal the role of the regime’s lobbyists to its readers. Hence they did not know that the pro-Bahrain opinion column they were reading was published at the behest of … Bahrain, an oil-rich kingdom of 1.2 million people that has been rocked by popular protests since early 2011.

The episode is a glimpse into the usually hidden world of how Washington’s Op-Ed pages, which are prized real estate for those with interests before the U.S. government, are shaped. It also shows how Lockheed gave an assist to a major client — Bahrain has bought hundreds of millions of dollars of weapons from the company over the years – as it faces widespread criticism for human rights abuses against pro-democracy protesters.

As Ken Silverstein reported in Salon last month, the kingdom is stepping up its Washington lobbying efforts. Here’s the latest example, as far as I can piece together from lobbying disclosures filed by Bahrain’s “strategic communications” firm, D.C.-based Sanitas International.

On Nov. 30, the Washington Times published an Op-Ed under the headline “Bahrain, a vital U.S. ally: Backing protesters would betray a friend and harm American security.” It was written by Vice Adm. Charles Moore (retired). Moore was formerly commander of the Navy’s Bahrain-based Fifth Fleet. From 1998 to 2002, Moore notes in his Op-Ed, he “had the opportunity to develop a personal relationship with His Majesty King Hamad bin Isa Al Khalifa, Bahrain’s leader, as well as many senior officials in his government.” Moore passed through the revolving door and is now regional president for Lockheed Martin for the Middle East and Africa.
