During an emotional appearance on Who's Talking to Chris Wallace, Kevin O'Leary recounted how Mark Cuban came to his aid during a difficult time in his political career. O'Leary, who ran for the leadership of Canada's Conservative Party in 2017, had to withdraw due to his inability to speak French. He faced $2 million in campaign debt, which he was legally required to repay within 24 months or risk imprisonment. Desperate for help, he reached out to Cuban, who immediately agreed to support him by attending a fundraising event. O'Leary became visibly emotional recalling Cuban's unwavering friendship, stating, 'He saved my ass.' Cuban, a mainstay on Shark Tank since season 3, will be departing the show to focus on family but plans to return occasionally to update on past investments.
