The video was released Thursday by conservative journalist James O'Keefe.
“The language used in this video about Greg Abbott is abhorrent,” Davis said in a statement. “Greg Abbott has persevered through great personal challenge to raise a family, have a productive career, and for that he deserves our respect.”
The comments were made by a Battleground Texas volunteer during an event organizing support for Davis.
"Since he's in a wheelchair and most the slogans are 'Stand with Wendy' and 'Stand with Texas Women', isn't that amazing to think of?" asks a volunteer. "He's in a wheelchair and we want to stand with Wendy?"
Another volunteer suggests that Abbott is unattractive.
"First of all he's not good-looking, he doesn't speak very well, he doesn't have a good personality, and he's in a wheelchair," a volunteer says, as people laugh in the background.
