Let's say Trump really did help them.
His need to have his ego stroked is what is silly. Why does he care what POS LaVar Ball said? He already took credit for getting those 3 bad hombres back to the US. Why not just move on, knowing the truth, rather than acting like a child about the whole situation?
Now, let's say that Ball is right, and Trump is taking credit for something he didn't actually do.
Or, let's say that Trump really did help, but the Chinese didn't communicate that to Ball, and he really believes that Trump had nothing to do with it.
Either way, both are acting like 8 year olds.
