Donald Trump sent fear down Hillary Clinton’s spine on Friday when he predicted she could face federal perjury charges over sworn testimony she gave to Congress.

“Hillary Clinton lied to Congress under oath when she said she turned over all of her work-related emails, and that she didn’t send classified information on her illegal server,” Trump said in Massachusetts, according to Daily Mail. “Meaning she may now face major problems for perjury.”

This could not hit Clinton at a worse time, as it comes just a week after the FBI reopened their investigation into her use of her personal email server during her time as Secretary of State. FBI Director James Comey made this decision after 650,000 emails were recovered from a laptop belonging to Anthony Weiner, a top aide’s estranged husband.

Many of these emails were reportedly linked to Clinton, causing Trump to call into question her claim that she deleted only emails that were unconnected with the State Department.

“The 650,000 emails include brand new emails not previously seen by authorities,” he said. “She said she gave them all in, right? She said, ‘gave them all in.'”

“Well, when we saw 650,000 we figured, ‘I guess there has to be some surprises.’ Wait ’til you see what they find in those 650, too. It won’t be pretty,” he added. 

“What a mess. And all she had to do is follow the rules, and assume people are watching or listening,” Trump continued, scolding Clinton. “She’ll be under investigation for years.”
