Hard to say who's lying here. There's no question that the Kennedy campaign is designed to be a spoiler for Biden, but Rita Palmer is also a Trumper who was at the Capitol on Jan. 6th and describes it as "99.9% peaceful." Via CNN:

Robert F. Kennedy Jr.’s campaign manager said on Wednesday that New York campaign staff member Rita Palma was fired after she told GOP voters in a meeting last week that preventing President Joe Biden’s victory was her “number one priority” and encouraged them to volunteer for former President Donald Trump in Pennsylvania.

“We terminated her contract for misrepresentation immediately upon seeing the longer video in which she gave an inaccurate job title and described a conversation that did not happen,” Amaryllis Fox Kennedy, Kennedy’s campaign manager and daughter-in-law, said in a post on X Wednesday evening.

Palma confirmed to CNN on Wednesday she is no longer employed by the campaign. She told CNN she believes Kennedy is “still by far the best candidate” and called the focus on her comments a “distraction.”
