If he had he would be in jail..
Once the court case concludes then the jury of his peers may (or may not) find him guilty. The judge may sentence him to prison.
If that is the case then you will have this proof you need. He will be in jail so then you can finally say "wow! Look, he's in jail. That means he's guilty."
Meanwhile don't forget he is still on the hook for nearly half a billion dollars after another judge determined he has engaged in other fraudulent business practices. The only reason he hasn't had to settle up that debt yet is because he is stalling with an appeal that he has very little chance of being successful with.
So it's only a matter of time.
. no one has investigated Trump until he ran for president.
Maybe a criminal with decades of skeletons in his closet should really try to keep a lower profile and not draw so much attention to himself huh?
This is why presedential candidates are usually so heavily vetted before they run. As soon as they put themselves out there then their past becomes fair game.
Remember in 2016 when people were asking for Trump's tax recirds and he kept lying and saying he couldn't release them because they were under audit? That worked for a good long while but it was only a matter of time before SOMEONE got hold of them. It is the same with all his other shady and illegal scandals.
The things that have come to light about Trump SHOULD be enough to doom any political candidate. You guys have formed this curious cult of personality around Trump though where you don't care if he is guilty. You'll continue making excuses for him no matter what. Your double standards on character traits when it comes to this clown are ridiculous.
... you are listening to propaganda...
Believe me I KNOW propaganda and fake news when I see it and I can tell you this is pure projection here.
It is YOU who is swallowing the cult kool aid hook, line, and sinker.
