"And, again, I wrote back there on June 23, so that we could publicly disclose what the integrity of the wellbore is, we could publicly disclose what the integrity of the geology around the wellbore, so that we could better understand. …"
Markey all but confirms that the government has knowledge of the condition of the wellbore, but is not permitted to release the information publicly.
Markey’s wrote the June 23 letter to pressure BP to publicly disclose the problems with the wellbore. This would have allowed the information to be released without Markey doing it directly.
However, the questions raised in his letter serves to inform the public about what Congress does know about the condition of the well, without directly stating the information as fact.
