Jack Schlossberg might not ever ever "process" the untimely death of his sister Tatiana Schlossberg, but it has made him all the more "motivated" to make the most out of his life.

The Kennedy scion, 33, is currently running for Congress to represent New York's 12th Congressional District, competing in a crowded primary race to replace Democrat Jerrold Nadler.

The primary will take place on June 23, just over two years after Tatiana was diagnosed with acute myeloid leukemia, and sixth months after her passing at age 35.

Jack, speaking with Vanity Fair about balancing a congressional campaign while grieving the death of his sister, confessed he doesn't think he will "ever process" his sister's death.

"The world will never be the same for me, not only since she passed away, but since she was diagnosed with cancer about two years ago," he maintained.

Noting she was his "best friend," he said: "We could finish each other's sentences. And no one loved me or was a bigger fan of me of anyone else than my sister."

"I miss her all the time. Every day I think about her," he maintained, though further shared that it "also really does motivate me to do everything I can with every waking moment I have, because I realize it could have just as easily been me." 

He continued: "I have an obligation to her, not just to myself, to make the most out of my precious life and all that I've been given in this life to give back to others and make sure that we can fund cures for the type of cancer that took her life, and for other types of cancer."

"So it's made me all the more motivated, engaged, and focused on making the most out of my life," he continued. "I think that there's no higher calling than, than public service, and to me, I think politics is a noble profession, and one that I would be fantastic at serving this district as. So she wanted me to win, and I intend to honor her by doing just that."

Tatiana and Jack are one of three children Caroline Kennedy, only surviving daughter of John F. Kennedy, shares with husband Edwin Schlossberg, with whom she also shares daughter Rose, 37, an artist and filmmaker married to restaurateur Rory McAuliffe

Tatiana, a celebrated environmental journalist and author, had been married to George Moran, a doctor, since 2017, and they were parents to two children, son Edwin, born in 2022, and daughter Josephine, born in 2024.

It was during and after giving birth to Josephine that doctors discovered Tatiana's cancer.
