Seriously? Cruz's former Communications Director on the day of the first Republican caucus?
This seems close to your allegation and it seems to show just what I said:
Cruz did not do this

Dana Bash did suggest that Carson was out— parsing the words is not impressive to me. The timeline suggests CNN did this.
The Cruz campaign did not say this.
