In Washington... The Lend-Lease Bill becomes law when signed by President Roosevelt. Important amendments have been made by Congress. A time limit has been placed on the operation of the act -- until June 1943 -- but a motion originally passed in the House forbidding US warships to give convoy protection to foreign ships has been defeated. Also to be allowed are transfers of ships to other countries solely on the presidential authority without reference to Congress. Lend-Lease is not an entirely disinterested act. Britain is compelled to go on paying cash for as long as this is possible (meaning British assets in the US must be sold below their true value) and it is forbidden to export anything containing materials supplied under Lend-Lease, nor can items wholly produced in Britain be exported if equivalent items are being supplied under Lend-Lease.
