Vice President Harris has chosen Minnesota Gov. Tim Walz to be her running mate, opting for a former high school teacher and Midwestern Democrat to complete a newly assembled presidential ticket. In a social media post, Harris said Walz’s “convictions on fighting for middle class families” stood out. Walz is scheduled to appear with Harris in coming days in each of the seven most competitive states — Pennsylvania, Wisconsin, Michigan, North Carolina, Georgia, Arizona and Nevada.
