which allowed him contact with children, and he went on to abuse other children before being sent to prison on a 15-year sentence in 2004. The prosecutor who ultimately and successfully prosecuted the case in the early 2000s said that when Prosser had the case in the 1970s, he was lacking sufficient information: "We were able to gather a wealth of information that far exceeded what Prosser had," he said, adding, "It's not fair to second-guess him now." When interviewed in 2011 one of the victims said that in 1978 he and his brother had not communicated detailed information about the abuse to the authorities, and that when the case came to trial in 2002, Prosser helped in the prosecution. During Prosser's 2011 run for re-election to the Wisconsin Supreme Court, the incident was revived in a political ad by a pro-union organization which claimed that Prosser did not investigate the abuse allegations and participated in a coverup. The ad was ultimately rated "Mostly False" by the fact-checking website, PolitiFact.com, which concluded that the ad omitted critical facts and created false impressions. One of the abuse victims, who had been critical of Prosser's decision not to prosecute, criticized the ad as "offensive, inaccurate and out of context." Prosser asked his opponent, Kloppenburg, to call for the removal of the ad—she replied that the First Amendment gave the group the right to run such ads. Assembly staffers used for campaigning In 2006, Prosser testified on behalf of Wisconsin State Representative Scott Jensen who was being tried on three felony counts of misconduct in office because his legislative staffers also performed campaign activity on his behalf. Prosser stated that during seven years of his own tenure in the Wisconsin Assembly, he had used his taxpayer-funded staff for campaigning—the same crime Jensen was eventually convicted of. Prosser was not charged, and defended the actions saying, "it was a different era and public expectations were quite different". However critics described this as illegal activity, and the Appleton Post Crescent, Prosser's hometown paper, found Prosser's admissions sufficient reason to endorse Prosser's opponent in the 2011 election, saying Prosser fell short of having the "unimpeachable integrity" required of a high court judge because he had admittedly "condoned illegal activity" while serving as an elected official. Altercations with other justices During a closed-door debate between the justices on February 10, 2010, Prosser called Chief Justice Shirley Abrahamson
