Answer:
Red herring fallacy
Step-by-step explanation:
A red herring fallacy is one that is aimed at diverting attention from the main subject of interest by providing irrelevant information. It is used to lead others to make false conclusions.
Real issues are avoided and only surface issues are presented.
In this instance the senator releasing her financial information to the public is a red herring fallacy aimed at diverting public attention to other senators who have done far worse in their finances.
