But EVERYONE in Congress knows their feel-good restriction has no force in law. They knew that when the wrote the appropriation bill.
That's the point.
In fact, Billary is using a "national security waiver" to bypass the Congressional restriction.
If there were no legality to it...it would be completely pointless for the SoS to evoke such a waiver.
Clearly, she doesn't view it as a "feel good" restriction.
