GOLDEN, CO — Donald Trump spoke out for the first time about the FBI investigation into Anthony Weiner on Saturday, packing his stump speech with doubts about the system and allegations that support his idea that the government and system are rigged against him.

While the GOP nominee spent weeks casting doubt upon the FBI’s investigation that cleared former Secretary of State Hillary Clinton of criminal wrongdoing over her private server back in July, the latest decision to review Clinton’s emails again as part of Weiner’s investigation seems to have reinvigorated Trump’s trust in the government agency.

No longer is Trump pleading, "investigate the investigation"; instead he said he is now hopeful that "justice at least can be properly delivered."

Trump quickly integrated the FBI's investigation news into his stump speech Friday, but added allegations to his riff Saturday — saying that he believes some of Clinton's deleted 33,000 emails "were captured yesterday" in the new wave of the investigation. There is no evidence that the deleted emails have surfaced or are included in the Weiner-related review.

It was the first time Trump brought up Weiner since FBI Director James Comey informed Congress about the new emails.

The GOP nominee brought up the FBI letter Friday but did not mention Weiner, a Congressman who resigned in disgrace amid a sexting scandal, and who is under investigation for allegedly sending inappropriate text messages and pictures to an underage girl.

The emails were found on a laptop used by Weiner, sources have told NBC News. Weiner's estranged wife, top Clinton aide Huma Abedin, had used that laptop to send emails to Clinton, the officials said.

Comey's letter said the FBI learned "of the existence of e-mails that appear to be pertinent" to the Clinton investigation, though he added that the FBI "cannot yet assess whether or not this material may be significant."

Trump called Weiner "a major, major sleaze" and gave himself credit for calling Weiner that even before the investigation news was made public.

The Republican nominee also targeted Abedin as the person who "knows the real story."

"I wonder, is she gonna keep Huma," said Trump, pronouncing Abedin’s name as "Uma" while he speculated about the fate of her employment. He added that he hopes "they haven’t given Huma immunity because she knows the real story ... she knows whats going on."

Throwing it in the face of unnamed naysayers who Trump says tried to tell him the Abedin-Weiner marriage and the Clinton server investigation had "nothing to do with each other," Trump said proudly: "it turned out, it does. Very serious stuff."

Despite Trump’s newfound confidence in the integrity of the FBI, he maintained his doubts about the Department of Justice and continued to shroud their role in the investigation in conspiracy theory.

"There are those, and I happen to be one of them, who think Hillary Clinton offered Loretta Lynch a reappointment as Attorney General," Trump alleged, with no evidence to support his claim.

He told the crowd that the DOJ was "fighting" the FBI’s investigation. Also mentioning Bill Clinton’s tarmac rendez-vous with the Attorney General, Trump said "this is what we mean when we call it a rigged system."

But the investigation and those parties involved in it weren’t the only examples Trump had of why he still feels the system is rigged. He led off his battleground Colorado rally by warning that "we have a lot of people watching you people that collect the ballot" and SAID he has a "real problem" with mail in ballots because he fears pro-Trump ballots won’t be counted correctly.

"Like people say, 'Oh, here is a ballot, here is another ballot, throw it away. Here is one I like, we’ll keep that one,'" Trump pretended his way through the mind of a theoretical ballot counter.

The former reality show star gave one last dig at Weiner, breaking off his morning standard stump speech topics of jobs, radical Islamic terror, and trade to say that Clinton’s emails are on "Anthony Weiner’s — wherever." The dramatic pause earned loud applause from the crowd.

"Oof" Trump reacted, giving the crowd more of what they wanted. "He’s bad."
