A post on social media described the demonstration as the “Scamdemic Protest/March.” It advised participants to “please refrain from wearing Trump/MAGA attire as we want our statement to resonate with the sheeple. No flags but informational signs only.

“This is a sharing information protest and march against everything COVID, Vaccine, PCR Tests, Lockdowns, Masks, Fauci, Gates, Newsom, China, digital tracking, etc.”

A livestreamed video of the gathering shows a group of protesters on a sidewalk as cars navigate cone-lined lanes toward the stadium, which served as a COVID-19 testing site for months. A Times photographer witnessed much of the incident.

Protesters carried signs that read “Save Your Soul TURN BACK NOW,” “CNN IS LYING TO YOU,” “RECALL GAVIN NEWSOM” and “TAKE OFF YOUR MASK.” Some handed out pamphlets to motorists who had their windows down. Some cars blared their horns as they drove by.
