Mexican citizen Jose Barron petitions for review of an order of the Board of Immigration Appeals (BIA), which upheld an immigration judge’s decision denying him asylum and withholding of removal. After careful review, we find no basis for granting the petition, as the BIA’s denial of relief was supported by substantial evidence on the record as a whole. See Cubillos v. Holder, 565 F.3d 1054, 1056-58 (8th Cir. 2009) (substantial-evidence standard for asylum claim; denial of asylum *690 dictates same outcome on withholding-of-removal claim based on same underlying factual allegations). Accordingly, we deny the petition for review. See 8th Cir. R. 47B.
