The GAO is our nation's attempt to answer the famous Latin question, Quis custodiet ipsos custodes? It is the primary audit organization of the federal government. Only in a budding dictatorship would such an office, and its review of the relevant law of the land, be dismissed or disparaged.
At this point, really, anyone who cannot see plainly that Trump is a corrupt law-breaking would-be dictator is so prejudiced and blind in their thinking that they are essentially immune to facts and reality checks. For such a person, politics has ceased to be about finding truths and deriving just and competent governance from them. If truth doesn't matter, then it's really just a role-playing game. You come in, take some potshots, have a few laughs.
I remember the Internet in the late 80s and into the 90s. It was amazing. Truth mattered. Learning was enhanced. People around the globe could really talk to each other. The vision of guys like Tim Berners-Lee and Jimmy Wales seemed like it might come to fruition. But no. Monetized, silo'd, monitored, full of rapidly breeding and delusional memes. Just another machine to keep everyone consuming. And track those patterns of consumption.
