 The effort was an unusual example of bipartisan collaboration on the internet with the right-leaning blogs Porkbusters and GOPProgress actively working with left-leaning TPMmuckraker.On August 30, 2006, after he had been identified as the only suspect by Porkbusters and one of two suspects by TPMmuckraker, a spokesman for Stevens confirmed that he placed a hold.The following day, Senator Byrd (TPMmuckraker's other suspect) also admitted to placing a hold stating that he had wanted to have more time to look at the legislation; he had lifted the hold by the time of the announcement.
