During the debate, Clinton directly confronted Trump about his position on Russian's alleged interference in the elections.
Referring to the WikiLeaks emails, Clinton said the "Russian government has engaged in espionage against Americans."
"This has come from the highest levels of the Russian government, clearly, from Putin himself, in an effort, as 17 of our intelligence agencies have confirmed, to influence our election," Clinton said.
"So I actually think the most important question of this evening, Chris, is, finally, will Donald Trump admit and condemn that the Russians are doing this and make it clear that he will not have the help of Putin in in this election, that he rejects Russian espionage against Americans, which he actually encouraged in the past?" Clinton told the debate moderator, Chris Wallace. "Those are the questions we need answered. We've never had anything like this happen in any of our elections before."
