Ah, HCR thinks so too, and of course says it better than i could:
This inquiry is not actually about wrongdoing; it is a reiteration of the same plan Trump tried to execute in 2019 when he asked Ukraine president Volodymyr Zelensky to smear Biden before the 2020 presidential election. By launching an inquiry, Republicans can count on their false accusations spreading through the media, tainting their opponents even without evidence of wrongdoing. See, for example, Clinton, Hillary: emails.
