Last year the Government Accountability Office issued “Public Relations Spending” (GAO-16-877R) in response to a request from the Senate Budget Committee. The purpose of the report was to “determine how much the federal government spends on public relations activities, including contracts and internal agency support, and identify the highest-spending agencies.”
“Public relations internal agency support” is defined in the report as employees classified as “public affairs specialists” (GS-1035s).
