"If I win, I am going to instruct my attorney general to get a special prosecutor to look into your situation. There has never been so many lies, deception — there has never been anything like it," Trump, the Republican presidential nominee, said at the debate in St. Louis. 
 
"When I go out and speak, the people of this country are furious. In my opinion, the people who have been long-term workers at the FBI are furious."
 
Clinton turned over emails she designated as work emails but deleted those she deemed personal. While FBI Director James Comey rebuked her handling of classified information as "careless," she was not charged with any crime. 
 
The FBI's investigation found a number of those deleted were actually work emails, a fact that Trump blasted Clinton for on stage. 
 
Clinton immediately pushed back at Trump's characterization of the situation, arguing, "It's good that somebody with the temperament of Donald Trump is not running this country."
 
But Trump immediately shot back: "Because you'd be in jail."
 
The debate has taken a historically negative tone right from the start as the candidates deal with the blowback related to the Friday release of video in which Trump spoke about grabbing women without their consent.
 
That video has sparked outrage from Republicans and Democrats alike. More than two dozen Republican lawmakers have called on him to step down from his presidential campaign.
