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 "He sent a memo dated April 20, 1961, to Vice President Lyndon B. Johnson, asking him to look into the state of America's space program, and into programs that could offer NASA the opportunity to catch up.". Is that enough to answer the question?
