Voicemails of CRuz campaigners giving orders to tell caucus attendees to tell others that Carson was out (which he was not).

Cruz contends that it was inside knowledge that Carson was going to suspend his campaign. Word leaked out, and they ran with it.
Politics isn’t “bean bag” like Jeb Boy says.
