Vice President Kamala Harris and former president Donald Trump are working hard to earn the support of a key voting bloc this election: union voters. While most major unions have kept up the tradition of backing Democrats by endorsing Harris, two of the country’s biggest unions — the International Brotherhood of Teamsters and the International Association of Fire Fighters — opted not to endorse either candidate, citing internal divisions among their ranks. April Verrett, president of the Service Employees International Union, joins us to talk about why her union endorsed Harris, and what’s driving divisions within unions. And in headlines: Georgia’s Republican secretary of state says local officials are prepared to fight election misinformation, A Nevada man says he’ll sue a California county sheriff who accused him of plotting to assassinate Trump, and NASA’s Europa Clipper spacecraft is on its way to Jupiter’s ocean moon.
