"Thank you, Huma. Good job, Huma," Trump said, referring to Huma Abedin, a top Clinton aide. "Thank you, Anthony Weiner."
The FBI discovered the emails on a device seized from Abedin's estranged husband Anthony Weiner, who is being investigated for allegedly exchanging sexually explicit messages with an underage girl.
Trump said emails -- the contents of which are unknown -- will be "absolutely devastating" to Clinton. The FBI is still working to determine if any of them are pertinent to the investigation into Clinton's private email server.
