It's so odd to talk about sex before a court case about sex. I'm surprised he's admitted to that.
I agree that this is him deliberately sowing seeds to downplay what he did ahead of the trial and a jury being selected. Discussing it in America and admitting doing the 'legal' part - while emphasising this is legal in the UK to paint it as acceptable to the US audience (as age of consent varies by state but culturally seen as 18+) - isn't
technically influencing a jury. But obviously it was going to get picked up by the press in the UK as well because of who he is, so it could be seen by his future jurors here.
This is him spin doctoring and controlling the narrative of "I didn't do anything illegal but now I'm a changed Christian family man, I realise that I should not have been having sex with schoolgirls when I was just an immature lad of 30" - conveniently not referencing the fact his court case is about him committing sexual assault and grooming/coercion and disregarding the consent she was able to give, not her age specifically.
It's an attempt to create plausible deniability/doubt about the actual abuse since he's openly admitting to an amount of inappropriateness with one defendant - but only the parts they can't prosecute him for. By publicly admitting he knew her and they did have sex, it puts all the burden on the prosecution to prove that the victim didn't consent and that he knew that (which is the most difficult part of any sexual assault case).
While that's often the case for sexual assault cases, most defendants
don't get national press coverage of their defense months ahead of the trial while their victim cannot publicly respond due to defamation/contempt of court laws
