The bill has more than 100 sponsors in Congress, with support from Democrats and Republicans alike. Outside of Congress, CISPA has the support of --if you count trade groups like the Business Software Alliance and CTIA. Individual sponsors include AT&T, Facebook, Intel, Microsoft, and Verizon.

Facebook's support, in particular, has drawn the ire of the bill's critics. In , Facebook's Vice President of U.S. Public Policy, Joel Kaplan, defended the company, saying Facebook will continue to safeguard users' private information and has no intention of sharing users' sensitive personal information.

TechDirt's that a promise not to abuse the bill's gray areas isn't good enough, because Facebook can't control what the government does with shared information. Besides, just because Facebook vows to protect private information doesn't mean other companies will, Masnick said.

The bill will be up for a vote in the U.S. House of Representatives the week of April 23. Unlike SOPA and PIPA, CISPA has no close relative in the U.S. Senate. Two larger cybersecurity bills, and , have been proposed, but haven't made it out of committee.
