Glass–Steagall critic cited Aldrich's involvement as evidence the Rockefellers (who controlled Chase) had used Section 21 to keep J.P. Morgan & Co. (a deposit taking private partnership best known for underwriting securities) from competing with Chase in the commercial banking business. After Glass introduced S. 245, he chaired a subcommittee that considered the bill and prepared a revised version while negotiating at length with the Roosevelt Administration to gain its support for the bill. By April 13, 1933, the subcommittee had prepared a revised Glass bill, but delayed submitting the bill to the full Senate Committee on Banking and Currency to continue negotiations with the Roosevelt Administration. President Roosevelt had declared on March 8, 1933, in his first press conference, that he opposed a guarantee of bank deposits for making the government responsible for the "mistakes and errors of individual banks" and for putting "a premium on unsound banking". Glass had reluctantly accepted that no banking reform bill would pass Congress without deposit insurance, but President Roosevelt and Treasury Secretary William Woodin continued to resist such insurance during their negotiations with the Senate subcommittee. On April 25, 1933, Roosevelt asked for two weeks to consider the deposit insurance issue. In early May, Roosevelt announced with Glass and Steagall that they had agreed "in principle" on a bill. On May 10, 1933, Glass introduced his revised bill (S. 1631) in the Senate. The most important change was a new provision for deposit insurance. As Roosevelt demanded, deposit insurance was based on a sliding scale. Deposit balances above $10,000 would only be partially insured. As Roosevelt had suggested, deposit insurance would not begin for one year. Glass limited the deposit insurance to Federal Reserve System member banks in the hope this would indirectly lead to a "unified banking system" as the attraction of deposit insurance would lead banks to become Federal Reserve members. Aside from the new federal deposit insurance system, S. 1631 added provisions based on earlier versions of the Glass bill that became Sections 21 (prohibiting securities firms from taking deposits) and 32 (prohibiting common directors or employees for securities firms and banks) of the Glass–Steagall Act. Steagall bill On May 16, 1933, Representative Steagall introduced H.R. 5661, which became the vehicle through which the 1933 Banking Act became law. This bill largely adopted provisions of the new Glass bill. Reflecting Steagall's support for the "dual banking system", however, H.R.
