Can a defendant bring a claim of improper vouching against a prosecutor?

Defendant contends the prosecutor improperly vouched for the credibility of the court-appointed experts by referring to his prior use of these experts and by openly expressing his admiration and respect for these witnesses. He, however, "failed to object, or seek an admonition, as to any of these remarks, and accordingly he cannot raise a claim of misconduct on appeal." (People v. Anderson (1990) 52 Cal.3d 453, 478, 276 Cal.Rptr. 356, 801 P.2d 1107.) Recognizing this hurdle, defendant also casts his claim of improper vouching as an ineffective assistance of counsel claim. We therefore review the merits of the claim, and we conclude that the prosecutor engaged in improper vouching but that defendant suffered no prejudice. Thus, reversal is not warranted.
