So heartbreaking! Hillary Clinton and the rest of her family are mourning the loss of her youngest brother, Tony Rodham, who sadly died at the age of 64 on Friday, June 7. The former Secretary of the State, 71, took to Twitter the next day to announce the devastating news along with a moving tribute.

“We lost my brother Tony last night. It’s hard to find words, my mind is flooded with memories of him today,” she wrote on the social media the following day. “When he walked into a room he’d light it up with laughter. He was kind, generous and a wonderful husband to Megan and father to Zach, Simon and Fiona. We’ll miss him very much.”

Hillary’s only daughter, Chelsea Clinton, echoed her mother’s bittersweet sentiment when she retweeted the thoughtful tribute. The death of Hillary’s brother comes during a joyful time for the family considering Chelsea, 39, is expecting baby No. 3 with husband Marc Mezvinsky.

Celebrities and fans alike took to Twitter to express their sincerest apologies for the What Happened author. “I am so very sorry for your loss. I know how utterly painful it is to lose a brother. Sending you heartfelt condolences and may his memory be a blessing and a comfort,” one user wrote to Hillary. “I’m so sorry Sec Clinton. You are a wonderful, fun and loyal sister,” comedian Kathy Griffin sweetly chimed in.

Over the years, Tony — who would’ve turned 65 this August — worked a variety of jobs, including gigs as a prison guard, insurance salesman, repo man, private detective and business investor. Although he never graduated, Tony also attended Iowa Wesleyan College and the University of Arkansas, according to The Washington Post.

Despite keeping mostly low-profile jobs unlike his sister, fans of the Clinton family can remember Tony from previous presidential elections. While Hillary’s husband and Tony’s brother-in-law, Bill Clinton, was in office, the former first lady’s late brother worked on the Democratic National Committee as an outreach coordinator. Then again in 2008, this time when his sister ran for president against Barack Obama, Tony worked as a consultant and businessman to help raise funds in Pennsylvania for Hillary’s presidential campaign.

Besides Hillary’s side of the family, Tony — who became one of the few people to get married at the White House — will leave behind his son Zach, shared with ex-wife Nicole Boxer, and son Simon and daughter Fiona, from his current marriage with wife Megan Madden.

The Clinton and Rodham families are in our prayers during this difficult time.
