Grassley's Twitter account hacked

Sen. Chuck Grassley's (R-Iowa) Twitter account was hacked on Monday by an opponent of anti-piracy legislation.

"Dear Iowans, vote against ACTA, SOPA, and PIPA, because this man, Chuck Grassley, wants YOUR internet censored and all of that BS," Grassley's account tweeted at about 1:30 p.m, referring to the Anti-Counterfeiting Trade Agreement, the Stop Online Piracy Act and the Protect Intellectual Property Act.

"Chuck is a supporter of SOPA, PIPA, and ACTA, meaning he wants no privacy for private accounts," the hacker tweeted later.

Although Grassley was a co-sponsor of the Protect IP Act, he was one of six GOP senators to urge Senate Majority Leader Harry Reid (D-Nev.) to delay a vote on the legislation. After last week's Web protests unleashed a wave of voter anger over the issue, Grassley pulled his support entirely.

The hacker claimed to be a follower of hacker-activist group Anonymous, which crashed the websites of the Justice Department and major movie studios and recording labels last week.

The hacker at one point said the password to Grassley's account was "icecream" and then later said it was "chuck 123."

At about 2:30 p.m., Grassley's office appeared to regain control of the account, and deleted all of the hacked tweets. 

Grassley's office did not immediately have a comment.
