The first presidential debate of the 2016 election season wrapped up after 90 minutes of fiery arguments as both candidates hurled pointed attacks across the stage. Hillary Clinton notably denounced Donald Trump for not releasing his tax returns, and Trump responded by criticizing Clinton's use of a private email server. Trump frequently tried to interrupt Clinton and spoke over her answers. The candidates also sparred over trade and taxes, and how to bring jobs back the the United States. Trump continued to deny having ever supporting the Iraq War, and he also said nuclear war is the world's "single greatest threat." Clinton said Trump "has a long record of engaging in racist behavior," citing his questioning of President Obama's citizenship. In the end, both Clinton and Trump said they would support the outcome of the November election. Their surrogates are currently in the debate spin room answering questions from reporters about tonight's performance. The next presidential debate will take place Oct. 9 at Washington University in St. Louis, Mo.
