This is the dan gabriel tweet at 7:07 pm, gabriel is Cruz' PR guy. I think all the other tweets follow his tweet timewise. Later on, he then turned around and blamed it on the Trump campaign. It was very very hard to find this because he deleted it sometime in the middle of the night caucus night...
What proof is there that Dan Gabriel actually works for Cruz. His twitter page emphatically denies that he works for any candidate.
