In 2017, Wall raised the story of a member of the Saskatchewan NDP who had been sexually assaulted in Question Period in response to a question about the Global Transportation Hub land deal. The story was raised without the consent of the victim, and Wall was criticized for politicising the issue of sexual assault. Interim NDP leader Nicole Sarauer described his remarks as "disgusting," and asked he withdraw his comments, and the victim took to twitter to demand an apology as well. After initially stating in the legislature that he would make "no apology," Wall later publicly apologized to the victim, saying he "was not aware" she "did not want the matter raised in this forum." It was described by Leader-Post columnist Murray Mandryk as "the worst of politics."
