EXCLUSIVE — The State Department is facing a congressional subpoena for failing to turn over records on programs Republicans say cultivated “censorship-by-proxy and revenue interference of American small businesses,” the Washington Examiner has learned.

The subpoena, which was served late Thursday by the House Small Business Committee, is the latest development in a one-year investigation into an embattled State Department-housed office called the Global Engagement Center, which the Washington Examiner reported granted $100,000 to the Global Disinformation Index. The latter group, which is based in London and has an affiliated nonprofit organization registered in the United States, works to pressure advertisers to boycott right-leaning media outlets.
