While the court recognizes that requests for testimony from a prosecutor trying a criminal case are generally disfavored, United States v. Ziesman, 409 F.3d 941, 950 (8th Cir.2005), “the defendant’s obligation to resort to alternative means of adducing factual testimony is not absolute,” United States v. Prantil, 756 F.2d 759, 763 (9th Cir.1985). See Id. at 764 (<HOLDING>). At this stage of the proceedings, the court

D: holding that district court had not abused its discretion in denying plaintiffs motion to amend complaint
