The speech that Cruz provided and was loaded into the teleprompters had the phrase “we must support the Trump-Pence ticket.” Cruz LIED, this is why even his own Texas Delegates were upset with him and GOP donors wanted to attack him.
Cruz was a snake. Trump had a contingency plan in place knowing the dishonest character of Cruz. You cannot spin this to a positive for Cruz and negative for the entire convention.
I don't believe that is true.
The phrase you are referring to (which has a thread where the teleprompter output is shown containing that phrase) was on the teleprompter during NEWT GINGRICH'S speech.
That means one of two things. Either they were assured that Cruz would endorse Trump, or they were trying to leave him no option but to endorse without looking like a backstabbing liar.
