How is this illegal?
You guys don’t seem to understand. The whole point of the investigation is the investigation itself. It’s a predatory process meant to keep pressure and fear on the Presidency for the sake of protecting the real criminals who have broken real laws against the interests of our country. They can sit and push on after virtual nothing-burger for years and years, all in an effort to snipe at people around the administration, cultivating an environment of fear and anger, all meant to disrupt any attempts to pursue justice against Hillary’s comrades.
Unilaterally shutting it down may not be what they are trolling for, but it would get them an enormous amount of political mileage into removing Trump or at least de-fanging him from going after said comrades. But the primary goal is to persist as jackals, forever biting and threatening, until a real miss-step is cajoled.
