America's bungled political and social response to the coronavirus exists side-by-side with a record-breaking push to create a vaccine with U.S. companies and scientists at the center.

Joe Biden introduces Kamala Harris in first joint appearance

Joe Biden formally introduced Sen. Kamala Harris as his running mate on Wednesday, telling a socially distanced audience in a Wilmington, Del., gymnasium: "I have no doubt that I picked the right person to join me as the next vice president of the United States of America."

Why it matters: Harris is a historic pick for vice president, becoming the first Black woman and first South Asian woman to be named to a major-party U.S. presidential ticket. "Kamala knows how to govern," Biden said. "She knows how to make the hard calls. She is ready to do this job on day one."
