Gave 324 billion dollars to the Iranian regime
I'm guessing that Trump created a way for him or his family to siphon off a chunk of this, and that's what prompted it to begin with. Man loves his slush funds, and maybe after the 1.8B "Reparation" fund was scrapped he needed to look elsewhere. I don't buy the pressure of the mid-terms forcing him to make a deal that looks this bad, even to his own party.
Dollars to donuts, he's found a way to enrich himself even further with this "investment" fund and it's the primary incentive for him to push this down America's throat.
