Conservative political commentator Candace Owens shared a video of Biden calling into a Harris event, which was the first time he had been heard from publicly since his diagnosis. During the call, which was broadcast to the assembled team via speakerphone held by Harris's campaign manager Julie Chavez Rodriguez, Biden praised the efforts of his former campaign staff.

"Here's the full tape of Joe Biden calling into a Kamala Harris event just moments ago. This is the first time anyone has heard from Biden in five days," the caption of the video, uploaded by Charlie Kirk, reads.

Owens added: "All of this is very bizarre. He needs to make an actual appearance, ASAP."

Newsweek also emailed spokespeople for Morgan, Owens and Schneider for comment on Tuesday.

While there are plenty of people questioning where the president is, there are also those under the trending hashtag who aren't as concerned about his whereabouts.

"'Where is Joe Biden' is truly the dumbest trending topic. We know where he is, isolating until his COVID case isn't infectious anymore. You know, like all of you should do when you get sick," one person wrote.
