A curtain backdrop appeared to collapse behind Republican presidential candidate Carly Fiorina as she spoke in a San Antonio campaign event.
Several women were seen rushing to shield Fiorina after the bunting and curtain frame crippled, sending frame piping and cloth falling to the ground.
After Fiorina returned to the front of the stage, she immediately asked if everyone was okay – then someone yelled "Trump!"
"Trump, Hillary, it could have been lots of people," said Fiorina.
There were no reports of injuries.
From there, she continued speaking to members of the National Association of Women Business Owners, and took questions, for another half an hour.
The event was at the Marriott Rivercenter in San Antonio. As of writing, no comment was given on what happened to the backdrop.
