The President to the Director of the Office of Scientific Research and Development (Bush)1
Dear Van: While the Prime Minister was here we discussed the whole question of exchange of information regarding Tube Alloys , including the building project.
While I am mindful of the vital necessity for security in regard to this, I feel that our understanding with the British encompasses the complete exchange of all information.
I wish, therefore, that you would renew, in an inclusive manner, the full exchange of information with the British Government regarding Tube Alloys .
