Passage: The speech, written by Charles Bohlen, contained virtually no details and no numbers. More a proposal than a plan, it was a challenge to European leaders to cooperate and coordinate.  It asked Europeans to create their own plan for rebuilding Europe, indicating the United States would then fund this plan. The administration felt that the plan would likely be unpopular among many Americans, and the speech was mainly directed at a European audience. In an attempt to keep the speech out of American papers, journalists were not contacted, and on the same day, Truman called a press conference to take away headlines. In contrast, Dean Acheson, an Under Secretary of State, was dispatched to contact the European media, especially the British media, and the speech was read in its entirety on the BBC.

Question: How was the speech kept from spreading in public?
journalists were not contacted
