Trump, no matter WHAT you believe, didn't start this, he didn't lie about Teddy as Teddy always does about himself and/ or his actions, and you don't know any American political history; obviously.
Here is Trump's exact quote:
"Lyin' Ted Cruz just used a picture of Melania from a G.Q. shoot in his ad. Be careful, Lyin' Ted, or I will spill the beans on your wife!"
Ted Cruz had nothing to do with the picture. It wasn't his ad. Trump lied about Cruz's involvement.
