Blanchette was mentioned in this article:

Also, in the prior Testimony of Andy Ramirez to the Committee on Judiciary in August 2006, pgs 45-46. On page 3 it says simply "SEALED HEARING OMITTED BY COURT ORDER." It looks like the defense got to question him, but only in a sealed hearing, not in open court.

(Snip)
One agent by the name of Blanchett who was subpoenaed by the defense was not allowed to testify. He would have testified that Rene Sanchez kept calling him about drug smuggling activities in Fabens and also when and where the busts were occurring. Agent
Blanchett made a report of this to the Border Patrol because he was suspicious of Sanchez and was reprimanded for doing so.
Homeland security agents went to Fabens to question Blanchett about his reporting the calls from Rene Sanchez. Agent Blanchett was asked questions without representation, and was requested to surrender his weapon. Blanchett requested representation, which he received from his Federal Law Enforcement Officer’s representative who then instructed Blanchett to leave during the questioning by DHS agents and Blanchett immediately walked out of the room.
I suspect Blanchett's testimony could have been very revealing.
