REWATCH the debate here
Both presidential candidates are still standing after the first presidential debate on Monday night at Hofstra University in New York.
The candidates sparred over everything from the origins of ISIS to the American economy.
Lester Holt, the moderator, did not fare so well. Critics on social media mocked his inability to control the candidates.

The next presidential debate is Oct. 9 at Washington University in St. Louis, Missouri.
UPDATE -- 10:34 p.m.
Holt brought up the fact that Trump has previously said Clinton doesn't have the stamina to serve as president.
"As soon as he travels to 112 countries and negotiates a peace deal, a cease fire or even spends 11 hours testifying in front of a congressional committee he can talk to me about stamina," Clinton said.
Clinton also slammed Trump saying, "A man who can be provoked by a tweet should not have his fingers anywhere near the nuclear codes."
UPDATE -- 10:23 p.m.
Trump brushed off Holt when questioned about his 2003 Howard Stern interview where he said, "I don't know maybe, who knows," when asked about whether he supported the war in Iraq.
He claims that he told Sean Hannity that he was against the war.
UPDATE -- 10:03 p.m.
Holt just questioned why Trump took so long to acknowledge the fact that President Obama is an American citizen.
Clinton claimed Trump recently acknowledged Obama's citizenship because he knew it would come up in the debate.
UPDATE -- 9:54 p.m.
Holt asked Clinton and Trump about the Black Lives Matter movement and the recent police shootings involving African-Americans.
"Everyone should be respected by the law and everyone should respect the law," Clinton said. She also said gun control is an important factor in stopping gun violence.
Trump has repeatedly praised stop-and-frisk and said those policies need to be brought back.
Holt asked Trump about stop-and-frisk being ruled unconstitutional in New York.
Trump replied, "it was a very-against-police-judge."
Holt then said, "The argument is that it's a form of racial profiling."
"No, the argument is we have to take the guns away from bad people," Trump replied.
UPDATE -- 9:52 p.m.
Trump to Clinton: "You've been fighting ISIS your entire adult life."
UPDATE -- 9:39 p.m.
Trump said the country has spent $6 trillion in the Middle East and he claimed the U.S. could have rebuilt its economy twice with that money.
"It's about time this country had someone running it who knows something about money," Trump said.
He also said America's airports look like something from a third-world country.
Clinton and Trump sparred over his tax returns.
Trump once again said that he will release his returns when he is no longer under audit.
Trump added that he would release his returns when Clinton released the emails she deleted.
Clinton suggested Trump was hiding something because he refuses to release his returns.
"Maybe he's not as rich as he says he is," she said. "Maybe he's not as charitable as he claims to be."
UPDATE -- 9:23 p.m.
Clinton and Trump went head-to-head over the North American Free Trade Agreement, also known as NAFTA.
UPDATE -- 9:15 p.m.
A theme throughout Trump's campaign has been that he will stop companies from outsourcing jobs. Early in the debate, Trump mentioned a list of companies that are building factories abroad. One of the companies Trump mentioned, Carrier, is a company based in Indiana where Trump's vice presidential nominee Mike Pence is governor. Earlier this year, Carrier announced that they are shipping more than a thousand jobs to Mexico. Is Trump undercutting his argument by bringing up the failure of his running mate to keep jobs in his state?
UPDATE -- 9:05 p.m.
The opening segment focused on creating jobs for Americans.
"First we have to build an economy that works for everyone, not just people at the top," Clinton said.
Clinton explained that this starts with providing a fair living wage and making sure women get equal pay for equal work.
Trump focused on preventing jobs from going overseas to places like China.
Trump said he and Clinton likely agree on how to help the economy but differ on numbers.
"We have to stop our jobs from being stolen," Trump said. He, however, seemed shakier when responding to moderator Lester Holt's questions about how he would bring manufacturing jobs back to the U.S.
Clinton framed the debate saying, "Who can put into action the plans that will make your life better?"
Clinton and Trump shake hands
Hillary Clinton and Donald Trump went head-to-head on the debate stage Monday night at Hofstra University in New York. This face-off is 18 months in the making and could be viewed by approximately 100 million Americans, according to CNN.
Officials said the 90-minute debate will be broken down into six, 15-minute "pods," with Clinton receiving the first question.
Clinton will have two minutes to answer and Trump will have two minutes to respond.
The rivals spent Monday preparing for the debate.
Clinton prepared by facing off against her former aide Philippe Reines, who played Trump.
Campaign sources told CNN that in one practice debate, Reines assumed the character of Trump and praised Clinton for being a pioneer for women.
The New York Times reported that Clinton advisers threw Trump-like assaults her way to test her responses. Clinton also reportedly tested out how to interrupt Trump without playing into gender stereotypes.
Prior to the debate, CBS reported that Clinton's name was misspelled on the debate ticket.
On the ticket, her name is spelled "Hilary Clinton." There should be two L's in Hillary.
Trump, on the other hand, watched videos of Clinton to prepare for the debate.
He didn't, however, hold a mock debate with someone standing in for Clinton.
Trump's preparation was more focused on making sure he is aware of the countdown timer while he's speaking, according to the New York Times.
His advisers reportedly worked to make sure he stays focused on big-picture themes rather than filling his head with facts.
