“James Hoffa, the former general president of the International Brotherhood of Teamsters, on Thursday night put out a blistering statement criticizing his successor, Sean O’Brien, for the union’s choice not to endorse a presidential candidate this election cycle,” the Daily Beast reports. “Hoffa, the son of the legendary labor leader Jimmy Hoffa, called the decision ‘a critical error’ and ‘a failure of leadership’ on O’Brien’s part.” Said Hoffa: “There is only one candidate in this race that has supported working families and unions throughout their career, and that is Vice President Kamala Harris.”
