I want to know the answer to the following question:
President Kennedy sent a letter on April 20, 1961 to who about the US's space program?
All the background I'm provided with is that "Based on this, Johnson responded to Kennedy, concluding that much more was needed to reach a position of leadership, and recommending that the manned Moon landing was far enough in the future that the US had a fighting chance to achieve it first.". Is that enough to answer the question?
