The following excerpt is from People v. Lugo, B275245 (Cal. App. 2017):
most, this was a permissible attack on the credibility of a witness, not an attack on defense counsel or the honesty of defense tactics. (See People v. Seumanu (2015) 61 Cal.4th 1293, 1337-1338 [prosecutor may challenge truthfulness of witness but may not imply defense counsel was personally dishonest or fabricated a defense].)
