'Jeopardy' superstar claims responsibility for Chuck Grassley's tweets

As Twitchy readers are well aware, we’ve spent a good chunk of time puzzling over Senator Grassley’s, shall we say, interesting Twitter technique. He’s certainly had us scratching our heads on occasion, but that’s been part of his charm. Say what you will about his tweeting style, but Grassley has proven his worth outside of the Twitterverse as a diligent truth-seeker in the Fast and Furious investigation.

Now that record-breaking “Jeopardy!” champ Jennings has stepped forward and jokingly claimed responsibility, suggesting that Senator Grassley is mentally impaired, is he also willing to admit he’s behind Joe Biden’s staggering garbage heap of gaffes? Because we’re pretty sure that Biden’s got Grassley beat in the WTF department.
