That means someone forged Killian's signature.

A crime.

Since a forgery has already been perpetrated and since Burkett obviously knows who did it, what is to stop a criminal investigation from going forward in which he is compelled to reveal his source? He is by no stretch of the imagination a journalist and therefore has neither a first amendment nor a fifth amendment reason not to reveal his source.
