Bolded content is mine - added to emphasize partisan nature of the two acts of congress.
http://en.wikipedia.org/wiki/Gramm%E2%80%93Leach%E2%80%93Bliley_Act - "GrammLeachBliley Act (GLB), also known as the Financial Services Modernization Act of 1999"
A year before the law was passed, Citicorp, a commercial bank holding company, merged with the insurance company Travelers Group in 1998 to form the conglomerate Citigroup, a corporation combining banking, securities and insurance services under a house of brands that included Citibank, Smith Barney, Primerica, and Travelers. Because this merger was a violation of the GlassSteagall Act and the Bank Holding Company Act of 1956, the Federal Reserve gave Citigroup a temporary waiver in September 1998. Less than a year later, GLB was passed to legalize these types of mergers on a permanent basis. The law also repealed GlassSteagall's conflict of interest prohibitions "against simultaneous service by any officer, director, or employee of a securities firm as an officer, director, or employee of any member bank."
Yes Clinton signed it - but it was planned, hatched and executed by three R's. Clinton was a willing dupe - not sure how the impeachment mess played into this but I am sure it did.
