In this May 22, 2008 file photo, Sen. Charles Grassley, R-Iowa is seen on Capitol Hill in Washington.
A person claiming to be in Osage (Osage, Iowa, presumably) and affiliated with the Internet hacker group Anonymous infiltrated the Twitter account of Iowa Sen. Charles Grassley this afternoon and sent more than two-dozen messages to his nearly 34,000 followers.
The messages sent mocked Grassley and mentioned controversial measures in Congress dealing with Internet piracy including the The Anti-Counterfeiting Trade Agreement (ACTA), Stop Online Piracy Act (SOPA) and the Protect IP ACT (PIPA).
"Dear Iowans, vote against ACTA, SOPA, and PIPA, because this man, Chuck Grassley, wants YOUR internet censored and all of that BS," said the first message, posted at around 12:28 p.m. CST.
Grassley was among senators who changed his stand on SOPA and opposed it after an outpouring of online opposition to tinkering with Internet freedoms. Grassley had signed on as a co-sponsor of the bill when it was formally introduced in May.
Grassley's spokeswoman Jill Kozeny says in an email that his office is "working to manage it."
