*1 Before GRUENDER, BOWMAN, and SHEPHERD, Circuit Judges.

____________

PER CURIAM.

*2 Sylvester Barbee appeals from the order of the District Court granting ^[1] summary judgment to defendants Cheri Ellis and Audrea Weekly in Barbee’s 42 U.S.C. § 1983 action arising from conditions of his confinement while he was held at the Cummins Unit. We agree with the district court that even assuming Barbee ^[2]

was incarcerated under conditions that amounted to a substantial risk of harm, he has shown no jury issue whether these defendants were deliberately indifferent to that risk. See Kulkay v. Roy, 847 F.3d 637, 643 (8th Cir. 2017) (noting that an official is deliberately indifferent if she fails to respond reasonably to a known substantial risk); see also Cullor v. Baldwin, 830 F.3d 830, 836 (8th Cir. 2016) (reviewing an order granting summary judgment de novo). We affirm the judgment.
