Kennedy family members endorse Biden over RFK Jr. at Philadelphia event

Members of the Kennedy family endorsed President Biden on Thursday at a campaign stop in Philadelphia -- a blow to the presidential campaign of Robert F. Kennedy, Jr.

Among the family members to publicly endorse Biden is RFK's sister was Kerry Kennedy.

"The Kennedy family endorses Joe Biden for president," she said.

As an independent who hasn't shown any signs of dropping out of the presidential race, Kennedy poses a threat to Biden.

His sister slammed Trump during her speech.

"I can only imagine how Donald Trump's outrageous lies and behavior would have horrified my father," Kennedy said in her speech at the event. "President Biden has been a champion for all the rights and freedoms that my father and uncles stood for."

Kennedy responded to his family members on his X account.

"We are divided in our opinions but united in our love for each other. I hold this as a possibility for America too," Kennedy said. "Can we disagree without hating our opponents? Can we restore civility and respect to public discourse? I think we can."
