The Latest: Harris and Trump campaigns pivot to turnout as early voting begins

With just 21 days remaining to cast votes this presidential season, Kamala Harris and Donald Trump are scrambling to win over key constituents as well as the other party's voters in what looks to be a razor-tight election. A Republican coalition is backing the Democratic nominee while she campaigns in Pennsylvania before sitting down for a Fox News interview. Trump will be in Florida and appear on TV Wednesday in town halls with women and Hispanics. Both campaigns are appealing for the votes of union workers in pivotal blue-wall states. And The Carter Center says former President Jimmy Carter, now 100 years old, has voted by mail.
