Well, I admit to being confused about this. Assuming the car was actually purchased & it was not from American military funds, but personal funds....why would they need money from outside sources if they could afford such an expensive car?
It wasn't. That was a another Russian-propagated lie.
The car wasn’t purchased and the Zelenskys couldn’t afford it anyway with an estimated wealth of about 20 million, and the aid is to support a nation at war, it isn’t something an individual pulls out of his bank account.
