After the December 7, 1941 attack on Pearl Harbor, manpower shortages threatened as productivity increased. Rogers approached the Army Chief of Staff George Marshall, and with his strong support she reintroduced the bill to the 77th Congress with a new upper limit of 150,000 women, and an amendment giving the women full military status. The amendment was resoundingly rejected but the unamended bill passed, and on May 14, 1942 President Franklin Delano Roosevelt's signature turned "An Act to Establish the Women's Army Auxiliary Corps" into Public Law 77-554.
