When Robert F. Kennedy Jr. endorsed former President Donald Trump on Friday, his siblings were there to offer their disapproval of this move.

His sister Kerry Kennedy said she was “outraged” by her brother endorsing Trump on MSNBC’s “Inside with Jen Psaki.” 

“So I’m outraged and disgusted by my brother’s gaudy and obscene embrace of Donald Trump. And I completely get out 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,” Kerry Kennedy said on Sunday’s show.

Kerry Kennedy, along with siblings Courtney Kennedy, Chris Kennedy, Rory Kennedy and former Maryland Lt. Gov. Kathleen Kennedy Townsend, posted a statement on X, formerly Twitter, of Friday after he made his announcement.

“We want an America filled with hope and bound together by a shared vision of a brighter future,” the Kennedy siblings wrote. “We believe in Harris and Walz. 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,” they added. 

On Sunday, Kerry Kennedy repeated her support for Vice President Harris and Minnesota Gov. Tim Walz on the Democratic ticket.

She said Robert F. Kennedy Sr. “would have detested almost everything Donald Trump represents.”

“I think … the stakes this November couldn’t be higher, which is exactly why my whole family will be fighting so hard to reelect Kamala Harris and Coach Walz, who’ve been champions for the values that my family has fought for, for years,” Kerry Kennedy said.

“Donald Trump is the polar opposite. He’s a threat to most basic freedoms that are core to who we are as Americans, the right for women to control our bodies, the right to live in communities safe from gun violence, to love who you love,” she said.

Kerry Kennedy stressed the importance of a Trump defeat.

“I think that Donald Trump is incredibly dangerous to us. And I think what Bobby has done here is anathema to everything. Not only [what] our family stands for, but what Bobby has given his life to. You know, he spent so many years out there working on protecting the environment. And that’s the opposite of what Trump plans to do,” she said. 

Jack Schlossberg, the only grandson of John F. Kennedy, Robert F. Kennedy Sr.’s brother and 35th president, also spoke out with a post on X.

“Never been less surprised in my life. Been saying it for over a year — RFKjr is for sale, works for Trump. Bedfellows and loving it,” he wrote. “Kamala Harris is for the people — the easiest decision of all time just got easier.”

Robert F. Kennedy Jr. also suspended his run for the White House as an independent Friday.
