What makes you think it's a case of foot-dragging and not a case of Kushner being to big of a risk to entrust with the security classification?
The perceived risk is an indication of jealous bias by the perceiver
If you go and read between the lines....whatever Jared wrote down on is original paperwork...was not factual about investments or financial affairs. I don’t think he sought to lie, but I think he felt it necessary not to lay out certain issues.
Because of that...he’s invited more criticism, and delays. If I were this guy, I’d just move on.
Frankly, anyone who has vast holdings and done creative accounting on taxes or bank-loans...ought not associate themselves in the government or invite background investigations. You’d be inviting trouble.
