The debate covered an array of issues, from politics to the environment and the border. Christopher Conover took a closer look at a few of the candidates' claims about the new NAFTA agreement and climate change.
When asked if the USMCA trade agreement between the United States, Mexico and Canada is an improvement from NAFTA, Democratic candidate Ann Kirkpatrick answered that the deal's specifications remain largely unknown. Contrary to her response, throughout the negotiation process, details about the agreement have been regularly released. Arizona Public Media also reported how USMCA would affect the dairy industry and other agricultural interests in Arizona.
Republican candidate Lea Marquez Peterson's response to a question about whether or not she accepted the science behind climate change drew audible laughter from the audience when she failed to provide a definitive "yes" or "no."
