If I follow you correctly, you're saying that we should not investigate or prosecute crimes committed by politicians¹ because the CIA did something on a TV show? That's an interesting point of view.

I am skeptical that doing so would result in greater concentration of executive power constrained only by political optics—given that that's what we're seeing now—and it is hard to envision a scenario of executive harassment of the legislature more obvious than what we've already seen² happen.

¹ to be clear, we're talking about things which actually happened in real life: https://en.wikipedia.org/wiki/Trump_fake_electors_plot
