The hacker collective Anonymous has vowed to take down all live streams of tonight’s State of the Union address and fill the event’s hashtag with protest tweets, according to a statement on one of the group’s Web sites.

At issue are the failed Cyber Intelligence Sharing and Protection Act, or CISPA, and a slate of other Internet laws.

“We reject the State of the Union. We reject the authority of the President to sign arbitrary orders and bring irresponsible and damaging controls to the Internet,” part of the statement reads.
