There's actually 2 of these cases but on one of them one of the charges Trump eventually admitted to was using 100K from a charity to pay off a lawsuit. So what was that about?
Turns out Trump had hired a contractor to put up a big flagpole at Mar a Lago so he could put up a huge American flag because he's a patriot. Trump then refused to pay the vendor. So the vendor sued, and Trump eventually settled for 100K. He then took 100K, from money donated for St Jude's Cancer center through his charity.
So he stole from a cancer charity to settle a lawsuit with a vendor over a flagpole for the AMerican flag.
