Donald Trump championed the news that the FBI is reviewing additional emails "pertinent" to previous investigations into Hillary Clinton's private email server as a game changer on Friday.

"This changes everything," he said to roaring crowds on the campaign trail that interrupted him with chants of "lock her up."

But much of Trump's rhetoric about the Clinton emails is riddled with errors, while the Democratic nominee herself obscured how the news of the additional email review was released.

We fact checked everything both candidates said on Friday, and will continue doing so here. Here's what they got right — and wrong — when talking about the FBI and the former secretary of state's emails.

"The FBI, after discovering new emails, is reopening their investigation into Hillary Clinton," Trump said in Lisbon, Maine, and Cedar Rapids, Iowa, on Friday.

False. This is not a reopening; as a technical matter, it was never closed. The FBI said they were reviewing emails that "appear to be pertinent" to previous investigations into Clinton's use of a private email server, but noted "the FBI cannot yet assess whether or not this material may be significant."

"This is the biggest political scandal since Watergate," Trump said at his rallies Friday.

Hardly. Bill Clinton was impeached by the House of Representatives for lying under oath to Congress about an affair he had with an intern; no one has found Hillary Clinton guilty of a crime to date.

"In brief remarks tonight, Hillary Clinton tried to politicize this investigation by attacking and falsely accusing the FBI director of only sending the letter to Republicans. Another Clinton lie. As it turned out, the letter was sent to both Republican and Democratic leaders in Congress," he said in Cedar Rapids, Iowa.

Clinton said the letter is "only going originally to Republican members of the House," which is not true. The letter was directed at Republican Congressional Committee chairmen and copied to ranking Democratic members, so Trump is right that she's blurring the facts to imply politicization. That said, he has spent weeks politicizing the previously completed FBI investigation as "rigged" and part of a global conspiracy.

"The FBI would never have reopened this case at this time if it were not a most egregious criminal offense," Trump said in Cedar Rapids, Iowa.

There is absolutely no evidence of this.

"We have not been contacted by anyone. First we knew about it is, I assume, when you knew about it, when this letter sent to Republican members of the House was released," Clinton said.

As noted above, the letter was released to the Republican Congressional Committee chairman — in both the Senate and House — and copied to ranking Democratic members.
