IsCompact.closure_subset_measurableSet

∀ {γ : Type u_3} [inst : TopologicalSpace γ] [inst_1 : MeasurableSpace γ] [BorelSpace γ] [R1Space γ] {K s : Set γ},
  IsCompact K → MeasurableSet s → K ⊆ s → closure K ⊆ s

If K is a compact set in an R₁ space and s ⊇ K is a Borel measurable superset, then s includes the closure of K as well.
