Vice President Kamala Harris will introduce her new running mate at a rally in Philadelphia on Tuesday evening. The choice of her running mate remains a mystery, with potential finalists including Pennsylvania Gov. Josh Shapiro, Arizona Sen. Mark Kelly, and Minnesota Gov. Tim Walz. Harris' campaign plans to announce the announcement via video message before the rally, similar to how Joe Biden revealed Harris as his vice presidential choice during the 2020 pandemic-marred race.
