It sounds to me like he did sign something after being worked over without a lawyer present because he says “I got played”
Okeefe said they wouldnt let him leave.
So they probably worked him over, exhausted him, twisted him up, and he signed something.
Waiting to see details
I am assuming there is a recording of the full interrogation. What was the wording on the document he signed because the Washington Post did publish it. I’m certain it didn’t say anything like “I recant my story” or anything like that. It must be something vague.
