I encourage you to read what he actually said rather than digest it through hit pieces, because it’s not even controversial.
He said that, hypothetically, if someone had sex with a victim of sex trafficking unkowingly - that is, the sex part was knowingly, but the victim of sex trafficking part was unknown, then it would not be fair to charge the man with rape.
If I kidnap a woman, sell her has a sex slave, and threaten her and her family that if she doesn’t walk up to you in a bar and act interested, and you mistake her for a willing participant, this obviously does not make you a rapist.
I don’t know if this is a willful distortion of what he said or what would motivate such a smear campaign, or if every is just shockingly bad at reading comprehension. But what he said was correct, and we all know it.
