ORDER AND JUDGMENT*
Jason Presley, a.k.a., Ernie Young appeals the district court’s dismissal of his civil suit. The ultimate relief sought by Mr. Presley is difficult to discern. Having reviewed Mr. Presley’s appellate brief and the record of his extensive proceedings in the district court, we find no meritorious claims and affirm.
Like the district court, we read the materials submitted by Mr. Presley to constitute a request that the federal courts order investigation and prosecution of various people for various crimes. Aplt. Br. at 3-8. And like the district court, we hold that such an order would improperly intrude upon the separation of powers. “Broad [prosecutorial] discretion rests largely on the recognition that the decision to prosecute is particularly ill-suited to judicial review.” Wayte v. United States, 470 U.S. 598, 607, 105 S.Ct. 1524, 84 L.Ed.2d 547 (1985).
Mr. Presley’s remaining allegations fail to state any cognizable federal claim that we can determine. While we will liberally construe the pleadings of a pro se claim*637ant, this liberality cannot transform “vague and eonclusory arguments” into valid claims for relief. Ogden v. San Juan County, 32 F.3d 452, 455 (10th Cir.1994).
For the foregoing reasons, we AFFIRM.
