WILMINGTON, Del. (AP) — Joe Biden is making his first appearance with newly chosen running mate Kamala Harris. The former primary rivals will appear together Wednesday at a high school in Biden’s Delaware hometown to discuss their shared vision for how to defeat President Donald Trump and then lead the country through a pandemic, its economic fallout and a long-simmering reckoning with racism. Harris and Biden then will sit down together for an online fundraiser designed to let small donors get a fresh glimpse of what the Democratic presidential ticket will look like. Democrats see Harris as having broad appeal. Trump and his allies cast her as left wing.
