Followed twitter feed to another site to another site. Anyways you get the picture. This story #TheThing leads back to Rubio #NeverTrump. It has been on the Hill twitter feed, Megyn Kelly etc. Best kept secret - not! MSNBC said it has been out there at least since January and did in fact originate with the Rubio campaign.
The scuttle has been around since the beginning of the year. I had assumed it referred to Rubio, not Cruz.
