 President Biden is in Delaware this weekend recovering from COVID. His running mate, Kamala Harris, is back on the campaign trail. NPR's Ozma Khalid reports. Vice President Harris is attending a fundraiser in Cape Cod, Massachusetts today. She's remained a loyal supporter of the president and is not publicly entertaining any of the speculation that she could take over and become the Democratic nominee for president if Biden drops out. But she's been out on the campaign trail.
