The suit, in a sense, amounts to Trump — the leader of the executive branch of government — asking the judicial branch to stop the legislative branch from investigating his past. To do so would break decades of precedent, which established that the legislature's investigative power is not limited to just researching possible legislation. Trump advisers have argued that the newest requests are fishing expeditions, broad-based inquires meant to extend beyond what should be in the investigators' purview in order to embarrass Trump and could set a dangerous precedent for future chief executives.
