The Cruz ad uses 43 of 143 words from the constituent's question and 24 of 615 words from O'Rourke's answer at the Aug. 31 town hall meeting in El Paso, The Dallas Morning News reported.

Cruz spokeswoman Catherine Frazier told the Morning News that she does not believe the clip is misleading.

"Congressman O'Rourke not only called burning the U.S. flag 'inherently American' but also said he was 'grateful' for those willing to commit such an act," she said. "His position is an appalling display of disregard to those who have put their lives on the line to preserve the very freedoms the American flag represents. Texans certainly do not share such views."

Evans, meanwhile, said O'Rourke has only spoken publicly about flag-burning once, when the congressman said he does not think anybody should burn the American flag.

"[Burning the flag] is nothing I’ve ever heard him talk about or suggest," Evans told The Hill.

Cruz has launched multiple attack ads against O'Rourke in recent days, slamming O'Rourke for cursing too much and getting a DWI more than 20 years ago.

Recent polls have shown O'Rourke and Cruz in a dead heat, a surprising feat for a Democrat in the deep-red state.

A video of O’Rourke defending NFL players who kneel during the national anthem has racked up millions of views after going viral last month.

In the video, O’Rourke, responding to a question at a town hall meeting in August, says he "can think of nothing more American" than the protests against police brutality and racial inequality.
