That's why I never watch those hearings or read whatever empty words these people say. Only care about actions. The hearings have pretty much become a way for politicians to grandstand for cameras and partisan politics while the CEOs get to lie and make untrue claims without any consequences.
I think it has accelerated in the last 5-10 years because of Twitter and other social media. I do not think the hearings such as the Church Committee Hearings are possible now a days.
Actions > Words.
