I want to know the answer to the following question:
Who was president Dwight D. Eisenhower's press secretary?
All the background I'm provided with is that "Four days later, at the Sixth Congress of International Astronautical Federation in Copenhagen, scientist Leonid I. Sedov spoke to international reporters at the Soviet embassy, and announced his country's intention to launch a satellite as well, in the "near future".". Is that enough to answer the question?
Answer: no
