His obstruction as Chair of the Senate Judiciary Committee would be historic, and according to legal experts is a violation of the U.S. Constitution.

Iowans have responded by gathering petition signatures (Why Courts Matter Iowa has gathered more than 7,500), rallying, delivering copies of the U.S. Constitution to the Senator, and taking to Twitter as well, sending a straightforward message with the hashtag: #DoYourJob.

Senator Grassley's Twitter feed is perhaps the most well-known among Senators, because he tweets for himself. And he tweets often. The #DoYourJob tweets appear to be getting through to Senator Grassley, because last night (Monday, March 14) he started using the hashtag #DoingMyJob in response.

Almost immediately, Grassley was sent a number of replies. The bottom line: no one was buying what he was trying to sell.
