Hillary Clinton's youngest brother Tony Rodham died Friday night, the 2016 Democratic presidential candidate announced Saturday on Twitter.
"We lost my brother Tony last night. It's hard to find words, my mind is flooded with memories of him today," she tweeted . "When he walked into a room he'd light it up with laughter."
Clinton went on to describe her brother, who was born in 1954, as "kind" and "generous" in the tweet. "We'll miss him very much," she said.
The cause of death is not immediately known.
Rodham is survived by wife Megan Madden and his three children: Zachary, Simon and Fiona. He was previously married to former Sen. Barbara Boxer's daughter, Nicole Boxer.
Rodham did not appear to play a major public role in sister Hillary's 2016 run for the presidency but did campaign with her during some stops in Pennsylvania.
In 2000, while his brother-in-law was president, Rodham successfully lobbied Bill Clinton to pardon a couple convicted of bank fraud who paid Rodham $245,000 for consulting work, according to a House Government Reform Committee report at the time .
Most famously a consultant, Rodham previously worked as an insurance salesman, a prison guard and a private detective. In 1996, Rodham coordinated "constituency outreach" for the Democratic National Committee.
Rodham said in 1999 that he had both benefited and suffered from his sister and President Bill Clinton's rise to power.
"It can go both ways," Rodham said at the time. "There's some wonderful things that have happened to me because of my relationship with Hillary and Bill, and there's been some really terrible things that have happened to me."
