It was a close call for presidential candidate Carly Fiorina and her supporters when part of the stage fell while she was speaking in San Antonio. 

The backdrop's drapes and supporting poles came crashing down, narrowly missing the Republican candidate and members of the audience. 

No one was injured and it's unclear what caused the accident.

Video of the moment was captured by a Texas Tribune reporter. After a delay, Fiorina continued her address to a gathering of female business owners.
