Johnson expresses the importance of maintaining funding for the program and the need for Jones' support in adopting amendments that would provide sufficient money for research and development. He also mentions that colleagues from the Minority are likely to side with the Administration on the issue. Johnson requests Jones' attendance and support at the meeting on April 5th.
