Kerry Kennedy, sister of Robert F. Kennedy Jr., declared that her father would’ve “detested almost everything” Donald Trump represents as she slammed her brother for endorsing the former president on Friday.

“I’m outraged and disgusted by my brother’s gaudy and obscene embrace of Donald Trump,” she told MSNBC host Jen Psaki on Sunday.

“And I completely disavow and separate and dissociate myself from Robert Kennedy Jr. in this flagrant and inexplicable effort to desecrate and trample and set fire to my father’s memory.”

Her comments arrive after the conspiracy theorist suspended his independent presidential campaign and endorsed Trump at a press conference only to later embrace him at a rally in Arizona.

She told Psaki that a number of Kennedy family members are backing Vice President Kamala Harris and Minnesota Gov. Tim Walz whereas Trump is a “threat to most basic freedoms that are core to who we are” as Americans.

Kerry Kennedy, a lawyer and activist who is president of the Robert F. Kennedy Human Rights organization, took to social media Friday after her brother’s endorsement to share a statement from his relatives condemning his Trump support.

“Our brother Bobby’s decision to endorse Trump today is a betrayal of the values that our father and our family hold most dear. It is a sad ending to a sad story,” read the statement.

Kerry Kennedy and other family members have made it clear where they stand on the conspiracy theorist’s politics, dropping by the White House for a visit with President Joe Biden in March and denouncing his candidacy shortly after his announcement last year.

Last year, she condemned her brother over his baseless claim that COVID-19 had a genetic structure that “ethnically targeted” certain groups.

RFK Jr. — whose 2024 bid was littered with controversies — has previously slammed Trump including roughly three months ago when he knocked him for having “scammed” American workers and criticized him for inflaming racial tensions during his White House term.

He’s since looked to redefine “what ‘MAGA’ really means” and painted the Trump slogan as one recalling a nation “brimming with vitality, with a can-do spirit, with hope and a belief in itself.”
