they'd only met once and it was never physical. This is another nothing-burger.

Report says she was sending him nudes pictures of herself.  This would comport with my above suggestion that she was throwing herself at him.  She has been engaged to someone else but they called it off.  Sad story of an Chad chaser dumping her boyfriend or husband for some Chad fantasy.  You know the end of these stories, pump and dump her. She ends up with nothing but her cats. Chicks are delusional.

She was a reporter, well aware of OPSEC -- you don't reveal your sources on purpose or by accident.  She's having an affair that would damage her credibility.  Yet somehow everyone around her knows about it?   Unlikely -- unless she herself wanted it to be known.
.
There are only two reasons I can imagine why she might want it known -- one is for status.  Capturing a Chad is a big status thing for chicks.  She might have been bragging, at risk of her career.  Seems risky, but chicks crave status.
.
Second reason is a woman scorned.  Possibly Bobby rejected her in some way.  So she leaks it to damage him, even though she knew it would blow back on her career.  But a woman scorned is not operating in a logical manner.
.
I don't think anyone could have found out about her sexting any other way that she herself either bragging like Monica Lewinsky (who was her Linda Tripp that outed her) or a revenge seeker for her own rejection.

Once you understand the nature of women, you can see thru the BS.  This was a woman scorned.  That's why she herself probably leaked the relationship to seek revenge on RFKjr.  Irrationally damaging her own career in the process.
.
You can see the same motivation in E Jean Carroll accusations. After all, she only went after Trump for denying her fantasy encounter.  The denial hurt her status seeking.  Therefore Trump must be destroyed.

Robert F. Kennedy Jr. is investigating a possible lawsuit against sexting New York magazine writer Olivia Nuzzi — who allegedly “bombarded him with increasingly pornographic photos and videos” while tricking him into unblocking her numbers, according to a mutual friend.
.
Kennedy, 70, has hired security expert Gavin de Becker to probe the saga because he is allegedly pursuing civil — and potentially criminal — litigation against the 31-year-old star political reporter, according to Jessica Read Kraus, who knows them both.
.
“This had nothing to do with romance,” de Becker said of the sordid saga. “He was being chased by porn.”

I, too, have been through Hell having insincere women throw themselves at me, but you learn a lot about spotting potential scams on the horizon in time to flip the script.   Lol
