Speaking at a rally in Fargo, Trump brought up his Democratic opponent once again, lamenting that she has not gotten over her defeat.

“Our opponent. Our wonderful opponent,” Trump told the crowd. “When is she going to get over it?”

The crowd then quickly broke into chants of “lock her up,” a staple of Trump’s 2016 campaign rallies.

“You know it is pretty amazing. Point after point, guilty, guilty, guilty, guilty, oh she’s OK,” Trump said, referring to the FBI investigation into Clinton’s use of an email server that led to no criminal charges.

“And then they go after us for a Russian hoax. Isn’t it incredible when you talk about a double standard? And nobody even looks at her,” Trump continued.
