I gave you the campaign explanation. It's up to you to prove it wrong.
I suspect that there is a first part of the video, that is cutoff, that shows where the money came from.
Just like I did not believe ME-shell Fields lying accusations... There is literally NOT one shred of video evidence to prove what Cruz campaign claims... And based upon the 'dirty' deeds of the Cruz campaign, I 'feel' more than comfortable to accept Cruz was in deed paying off somebody. I will readily admit IF I turn out to be wrong... But it is NOT up to me to prove Cruz is NOT a crook. It is his job to prove he is who he claims to be.
