"The answer is a shocked TV street reporter:Shocked reporter says NO one showed in support of Biden and Harris at their in event in Arizona."
"With nobody visible on the street outside, the reporter said, 'Pretty much all the people we saw who pulled into the parking lot about 45 minutes ago were with the Biden-Harris campaign or the pool reporters.'"
