The running influencer also faced backlash after fans accused her of deleting comments and blocking them. According to the New York Post, Tim Walz's daughter, Hope Walz, ranted about the influencer having the interview with her dad still pinned on her account. Hope Walz stated:
I’m not going to tell anyone what to do with their page, but I think it’s insulting to my dad to leave a certain video pinned, especially when he stands for quite literally the opposite of what the administration is doing.
