GOP Candidates Spar in First Presidential Debate

Eight Republican candidates trailing former President Donald Trump in the polls vied for second place Wednesday in the first primary debate. The candidates traded barbs and one-liners in a high-stakes contest at Fiserv Forum in Milwaukee, Wisconsin. Each of the candidates touched on some of the nation's hot-button issues, including crime, abortion and climate change. Interruptions were widespread. Many candidates talked over their peers, at times making it difficult to hear what was said. But the issues at the U.S.-Mexico border brought out some of the strongest rhetoric of the evening.
