An amendment introduced to the controversial CISPA bill by perennial big government advocate Rep. Sheila Jackson Lee would empower the Department of Homeland Security to intercept online IRS tax returns and any other Internet traffic deemed to transit networks owned by the federal government or operated on its behalf.

“Jackson Lee’s amendment (PDF) is broad enough to sweep in government contractors and university networks such as Internet2 and CENIC, said a telecommunications attorney who did not want to be identified because of client sensitivity. It also appears to cover open Wi-Fi networks run by federal agencies and networks in government-provided housing,” reports CNet’s Declan McCullagh.
