There is no direct quote from her or proof that she actually said this. Wish there was.
Yes, she probably said exactly this, perhaps in stronger terms, but unless a first-hand witness testifies, hopefully in the press, we have nothing.
The White House occupants and staff may be arrogant enough to say this in private but even if they did slip up and make a public utterance, the MSM would scrub all references.
"On that day, when all the nations of the earth are gathered against her, I will make Jerusalem an immovable rock for all the nations. All who try to move it will injure themselves."
Zechariah 12:3
She might not have said it, but you know she thought it. “Promises To Hurt Israel” Ha ha! She cannot hurt the “Apple of God’s eye”
