Republican Texas Senator Ted Cruz found himself in an awkward exchange with a critic during a campaign stop in Austin last Wednesday.

Video of the encounter was uploaded to YouTube and has been shared by various media outlets. The footage shows a woman approaching Cruz and reading the following statement:

“I’m a woman over 50 who, as of February 7th, has seven active pre-existing conditions. I’m not counting being female and a survivor of abuse. I purchase my individual policy on the health insurance exchange. If you force me into a high-risk pool, you will either bankrupt me or kill me. I take your threats of medical aggression personally and seriously and, I can assure you, I’m not the only Texan who does. My question is, ‘Will you pledge to submit to a DNA test to prove that you’re human?’”

Cruz responded with disgust, saying, “Ma'am, if you want to engage in insults that's your prerogative, but I'm not going to reciprocate. Thank you for being here."

Cruz will face off against Democratic El Paso Congressman Beto O'Rourke in November's Texas Senate race.
