Apparently you don’t get it.
Cruz has no connection, control, or say over this PAC. If he did, he would be doing something illegal and would be criminally prosecuted.
Just an act of coordinating the best TV ad placement between his presidential campaign and that PAC is criminal by law. He has no say over what they do.
He does not need to “disavow” or “plead ignorance”.
He is not going to win a single primary.
