Political writer Olivia Nuzzi has accused ex-fiancé Ryan Lizza of potentially outing her fling with Robert F. Kennedy Jr. after a months-long harassment and blackmail campaign that included allegedly stealing and hacking her devices, according to a bombshell filing.  

Nuzzi, 31, was granted a no-contact order against Lizza, one of Politico’s most prominent bylines, on Tuesday in Washington, DC court after she claimed he harassed her following their breakup earlier this month, CNN reported.

She alleged that Lizza, 50, “explicitly threatened to make public personal information about me to destroy my life, career, and reputation — a threat he has since carried out.”

Nuzzi’s career was derailed last month when she was placed on leave by New York magazine after she admitted to having a personal relationship with RFK Jr. after profiling his independent presidential campaign last November. 

Nuzzi reportedly started sexting with Kennedy, 70, shortly afterward the profile — and allegedly sent him “demure nudes.”

The one-time independent presidential candidate claimed the two only met in person once — and sources around him have alleged she was the pursuer. However, other reports claimed the fling started after he grabbed her hand while hiking for the profile piece. 

Nuzzi alleged in the court filing against Lizza that he orchestrated her fall from grace at the glossy magazine, claiming he potentially “through a third party or anonymous channel,” tipped her job off to what she only calls “the matter.”

Lizza, who covers Washington, has strongly denied all allegations.

“I am saddened that my ex-fiancée would resort to making a series of false accusations against me as a way to divert attention from her own personal and professional failings,” he told The Post.

“I emphatically deny these allegations and I will defend myself against them vigorously and successfully.”

Nuzzi’s no-contact order, which a judge granted on Tuesday, is a typical action in domestic disputes, CNN reported.

Lizza allegedly swiped and hacked an electric device that Nuzzi owned, and then tried to dole out information about her to the media, according to the court filing obtained by CNN.

Some of the shopped-around intel might have been “doctored” to further damage her, the court filing alleges.

And she claimed Lizza impersonated “an anonymous campaign operative” in order to give a political campaign information that would also hurt her, CNN reported.

Lizza also allegedly threatened her with violence so that she would “assume his share of financial responsibility” tied to a joint book deal they had, per the court docs.

The DC judge reportedly signed off on Nuzzi’s request to temporarily bar Lizza from contacting her and to stay clear of her workplace. When she goes to the home the two used to share earlier this year, police will accompany her, the judge also approved.   

Nuzzi’s legal fight with Lizza in court comes as her magazine conducts a “more thorough third-party review” of Nuzzi’s work after an internal probe found no evidence of bias.

Lizza previously said he would not write about RFK Jr. in Politico’s well-read Playbook because of his relationship with Nuzzi.
