The companies commended the bill for its transparency measures, including providing tech companies with the ability to publish information about the number and kinds of surveillance requests they receive.

The initial recipients received updated copies of the letter that included LinkedIn’s signature on Friday, said aides to the bill’s authors, Rep. James Sensenbrenner Jr. (R-Wis.) and Sen.

Last month LinkedIn joined Google, Facebook, Microsoft and Yahoo in suing the federal government at the court that oversees surveillance activities for the ability to publish more information about the surveillance requests they receive.

The Department of Justice responded by saying the companies would aid terrorists and jeopardize national security by publishing more information, but the companies vowed to keep pursuing the lawsuits.
