Petitioner Eduardo Padron Zequeira, a citizen of Cuba, seeks review of a decision by the Board of Immigration Appeals (“BIA”) that denied P *2 request for asylum, withholding of removal and protection under the Convention Against Torture (“CAT”) . We have jurisdiction under 8 U.S.C. § 1252 and deny the petition for review.

1. Substantial evidence supports the agency’s adverse credibility finding. Garcia v. Holder , 749 F.3d 785, 789 (9th Cir. 2014). The immigration judge (“ IJ ”) noted that the extent of P injuries “seem [s] to expand with each telling .” Indeed, Petit ioner’s description of the events of November 7, 2018— the most severe interaction that Petitioner allegedly had with Cuban officials before he came to the United States — evolved. During P etitioner’s credible fear interview, he stated that the police hit him in the stomach and slapped him in the face. In his asylum application, Petitioner stated that the police beat him with batons. Then, while testifying in front of the IJ, Petitioner said for the first time — that police stood on his knees and caused pain that recurs to this day. Although the omission of details cannot form the sole basis of an adverse credibility finding, Bandari v. INS , 227 F.3d 1160, 1166 – 67 (9th Cir. 2000), inconsistencies and embellishments in the basis of the asylum claim are sufficient to support an adverse credibility determination, Zamanov v. Holder , 649 F.3d 969, 973 (9th Cir. 2011). Considering that P etitioner’s basis for seeking asylum is persecution due to political opinion, inconsistent *3 statements about the severity of the harm that he suffered at the hands of government officials rise above the level of mere omission of detail . Petitioner’s explanations— which fail to explain his omissions do not compel a contrary result.

2. Substantial evidence supports the agency’s determination that Petitioner failed to present sufficient corroborating evidence to rehabilitate his testimony or independently meet his burden of proof. Petitioner provides no explanation for why he lacks medical documentation to support his claim. In his briefing, Petitioner relies on his testimony before the IJ where he stated that “[his doctor was] only able to do a certificate like as an employer because otherwise they are not able to do it.” This comment does not compel us to conclude that corroborating evidence is unavailable to Petitioner. 8 U.S.C. § 1252(b)(4).

3. In his opening brief, Petitioner did not argue that the BIA erred in rejecting his claim for CAT protection. Therefore, Petitioner has forfeited that issue. Rizk v. Holder , 629 F.3d 1083, 1091 n.3 (9th Cir. 2011).
