House representative Mike Rogers (R-MI) introduced a bill back in November called the Cyber Intelligence Sharing and Protection Act (H.R. 3523) or CISPA. It has since been referred to and reported by the appropriate committees. Since then, according to Representative Rogers' own web site, over 100 members of congress have already announced their support for the bill:
The 105 co-sponsors of the bill include 10 committee chairmen. Additionally, a wide range of major industry and cyber associations, such as Facebook, Microsoft, the US Chamber Commerce, the Business Roundtable, the Internet Security Alliance, TechAmerica, and many others have sent letters of support for the bill. A list of major industry and association supporters can be found at http://intelligence.house.gov/bill/cyber-intelligence-sharing-and-protection-act-2011
Unlike SOPA and PIPA, CISPA is all about collecting and sharing "cyber threat intelligence" and has less to do with copyright infringement concerns. This bill does not directly threaten the business interests of web companies, which means we should not expect their help in fighting the bill. In fact Facebook, IBM, Intel, Oracle, and Microsoft (among others) have already sent letters in support.
