After a hacker hi-jacked his Twitter account on Monday, Iowa Senator Chuck Grassley says he has a new, better password in place and his Tweets are now his own.

Someone claiming to be with the group “Anonymous” sent messages to Grassley’s 34,000 followers, making fun of the Iowa Republican and talking about legislation dealing with Internet piracy. Grassley says it was an unsettling experience.

“You feel violated from the standpoint that when somebody uses your name, they’re stealing the most personal aspect of your life,” Grassley says. “Why would people want to steal like that?” Grassley says the incident has been reported to Twitter and to the Senate’s Sergeant at Arms.

He couldn’t say yet if he’d pursue charges, should the hacker be caught.
