Is a prosecutor misconduct if they attacks the integrity of defense counsel?

" ' "A prosecutor commits misconduct if he or she attacks the integrity of defense counsel, or casts aspersions on defense counsel." [Citations.]' " (People v. Seumanu (2015) 61 Cal.4th 1293, 1336-1337 (Seumanu).) "A prosecutor may vigorously challenge the validity of any defense, and can characterize the testimony of a witness, including the defendant, as untruthful, but to state or imply that defense counsel has fabricated a defense is generally misconduct. [Citations.]" (Id. at p. 1337.)
