What if…..
Cummings' house was robbed because of the possibility of there being a large amount of cash stashed at his house is likely very high. (to avoid a paper trail, to avoid having to report it, and to not have to pay taxes)
Even better, what if Cummings got someone to rob his house for him now that he is worried that his house might get raided.
Maybe this is why Trump felt it important to tweet.
