There were fireworks between Hillary Clinton and Donald Trump as the two candidates faced off in the first presidential debate at Hofstra University.
Clinton and Trump engaged in 90 minutes of nonstop debating, moderated by "NBC Nightly News" anchor Lester Holt, to make their case to American voters, explaining why they thought they should occupy the White House.
Here are the most memorable lines of the first presidential debate:
Trump checked in with Clinton to make sure she was OK with him using her title of "Secretary" in the midst of criticizing her -- and her husband, former President Bill Clinton's -- stance on NAFTA.
Trump's response to Clinton's claim that he wished for the Great Recession and housing collapse so that his company could capitalize.
In the midst of a back-and-forth disagreement over Clinton's support, or lack thereof, for the Trans-Pacific Partnership (TPP), Clinton accused Trump of imagining her stance.
After Clinton claimed that, unlike Trump, she had a plan to fight ISIS, Trump made the accusation that Clinton has dealt with the current crisis in the Middle East for the length of her political career.
This was Clinton's claim after Trump attacked her over companies moving jobs out of the country. Trump's response to Clinton's line: "Why not?" To which Clinton said, "Why not? Yeah, why not? Just join the debate by saying more crazy things."
After a discussion about how Trump has repeatedly declined to release his tax returns until an IRS audit is completed, Trump explained what Clinton would have to do to get him to deliver them sooner. The audience broke decorum by applauding the Republican nominee. Moderator Lester Holt interjected at the conclusion of Trump's remarks by "admonish[ing]" the audience and asking for silence.
After sharing the story of an architect who claims he wasn't compensated for his work on the clubhouse of one of Trump's golf courses, Clinton invoked her father, Hugh Rodham, who owned a drapery fabric business.
Trump took offense after Holt responded to the candidate's praise of stop-and-frisk practices by explaining the police tactic had been ruled unconstitutional. "It went before a judge who was a very against-police judge," continued Trump. "[New York City Mayor Bill de Blasio] refused to go forward with the case. They would have won an appeal."
Trump took credit for getting President Obama to release his birth certificate in the midst of the "birther" controversy of his first term. When Holt asked the candidate why it took him so long to believe that Obama was born in the U.S., Trump tried to blame former surrogates of Clinton's for originating the dispute and said that after he got involved, he ended it.
As the discussion turned to the hacking of the Democratic National Committee's emails, Trump mentioned speculation that a foreign nation -- perhaps Russia or China -- was behind the attack, then offered another possibility.
"Wrong," was Trump's immediate response to Clinton's statement. The issue has been debated at length throughout the campaign with fact-checkers pointing to Trump's endorsement of military action in the country in a September 2002 interview with Howard Stern six months before the war began.
When Trump claimed again that he opposed the Iraq War, Holt fact-checked the candidate.
Clinton was excited to speak again after Trump and Holt's testy Iraq War exchange.
Trump's response to Clinton's oft-repeated claim that "a man who can be provoked by a tweet, should not have his fingers anywhere near the nuclear codes."
Trump's answer after Holt asked what he meant when he said that Clinton doesn't have "a presidential look."
Clinton's rebuttal to Trump's comments on her lack of a "presidential look."
Clinton and Trump, respectively, answer the debate's final question: Will the candidates accept the results of the election as the will of the voters?
