When was Sgt. Cobb interviewed?

[RJNorton]

So....when WAS Cobb questioned?

Heath, I checked Steers and Edwards, and as far as I can tell his pre-trial questioning is undated. Maybe someone else can see a date where I can't. John Fazio also discusses Cobb's pre-trial questioning in Decapitating the Union, but I do not see a date when it happened.

Jerry Madonna, in A Threat to the Republic, argues that Cobb was heavily coached prior to taking the stand during the trial. As we have discussed before, Madonna feels both Booth and Herold had passes to cross the bridge that were issued by Andrew Johnson, and Stanton wanted to make sure Cobb did not reveal this at trial.
