My post from 3 hours ago:
In letter to Nunes, Judge Collyer clearly states:
"I write in response to your letter of February 7, 2018, in which you request that the Foreign Intelligence Surveillance Court confirm whether "transcripts of relevant FISC hearings associated with" matters described in the letter exist and, if so, provide copies to the Committee. As you know, any such transcripts would be classified. It may also be helpful for me to observe that, in a typical process of considering an application, we make no systematic record of questions we ask or responses the government gives."
