Swagger was doing 55 in a 45 and he had a small amount of marijuana on him and in his system. The amount in his system would equate to 3 times UNDER the legal limit for drinking. So, while the WWE surely isn't happy, he wasn't shooting heroin while an underage prostitute blew him. He isn't a Kennedy.
If the plan was for him to win the title at Mania, I think he will still win the title.
