Defendant-Appellant Lamont C. Fitch appeals his sentence of six months for assaulting a safety manager while an inmate at United States Penitentiary, Big Sandy, in Inez, Kentucky. The district court’s decision, after considering the factors in 18 U.S.C. § 3553(a), to make the six-month sentence run consecutive to Fitch’s ongoing unfulfilled sentence was not an abuse of discretion. See United States v. Watford, 468 F.3d 891, 915-17 (6th Cir. 2006); United States v. Gibson, 896 F.2d 206, 210 (6th Cir. 1990). The district court’s decision to impose a six-month sentence, after considering the factors in 18 U.S.C. § 3553(a), was neither procedurally nor substantively unreasonable. See United States v. Jones, 445 F.3d 865, 869 (6th Cir. 2006). Therefore, we AFFIRM the district court’s decision.
