I guess the Repubs are just going to discredit any investigation undertaken by the Dems and whine that it's a crooked witch hunt and fake news, per usual.
Which it is, a crooked witch hunt that the democrats will exploit for as long as they can, and this 'investigation' would allow them to do so for a lot longer. This isn't about law and order, this is about the democrats' penchant to weaponize our justice system for their political purposes/gain.
What we have here is a group of people who broke the law and are now facing prosecution in court for it. Which as far as I know has not yet risen to the level of "insurrection", "treason", or anything close to that. And as far as I know there is no evidence that Trump or anyone else associated with him had anything to do with that event. NOTHING. If there was, you can bet your ass the media would be highlight it in the largest font they have and talking about nothing else for months. That is today's reality: **** Trump any which way you can.
And there is already an ongoing investigation(s) by the appropriate LE agencies, are there not? So, absent the political aspect, there is no gain whatsoever for a commission that will arrive at 2 different reports: one by the democrats that alleges but does not prove misconduct or involvement by Trump or his associates that is similar in vein to the Mueller Report on Russian Collusion, and another one by the Repubs on committee that discredits the democrats' report. And back and forth they'll go about it, all next year.
And so, just what we need, yet another example of partisan bullshit. They're not going to prove anything, and they're not going to unearth any new information. My guess is that the committee democrats will look for any Trump associate they can squeeze really hard to admit to something that is illegal or immoral, maybe even something they didn't even do. How? By threatening them with financial ruin or by threatening a family member with other investigations, like they did with Gen Flynn.
Let me briefly explain how the justice system is supposed to work. If a person is suspected of a crime, you're supposed to have some evidence that they did indeed commit that crime. And it can't be a bullshit opposition hit piece inspired by and paid for by the democrats or those close to them. It should have some credence to it and it should be verified; IOW, you don't go looking for a crime that you can pin on somebody. So let's not pretend that the democrats are looking for justice here, okay? They're looking for any dirt on Trump and co. and they want to do it on our dime and on our time.
