So what does Putin have on T-rump?

It will eventually come out - hopefully sooner rather than later - but the question is, what does Putin have on T-rump? It's certainly not something as an embarrassing 'pee pee tape' (T-rump's base would enjoy that rather than abhor it), so it has to be money loaned/laundered to him (or the Kushners) . The question is: how much?

It's got to be a substantial amount, one that has T-rump completely under his control like a puppet lest he 'calls it in'. How much?
