Donald Trump said Sunday that a trove of 650,000 emails found on disgraced former congressman Anthony Weiner's personal computer could be 'the mother lode' that sinks Hillary Clinton's presidential aspirations.

But he stopped short of declaring during a Colorado rally FBI investigators would find a smoking gun when they sift for work-related messages Clinton failed to hand over on her own.

'I would think they have some real bad ones, but we're going to find out,' Trump told about 3,000 people gathered in the University of Northern Colorado's basketball arena.

'Hey – maybe not. Maybe not.'

Donald Trump said Sunday in Colorado that 650,000 emails housed on disgraced former congressman Anthony Weiner's computer could contain 'the mother lode' of lost messages that Hillary Clinton ordered her lawyers to destroy

The Republican presidential candidate rallied thousands at the University of Northern Colorado's basketball arena, saying: 'This could be the 30,000 that are missing!'

Hours earlier in Nevada, the Republican White House nominee cast the latest wrinkle in the Weiner saga as a twist of fate.

'We never thought we were going to say "Thank you" to Anthony Weiner!' he exclaimed in Las Vegas.

The afternoon Colorado speech – his second stop in a three-state day – leaned heavily on vocabulary the Greeley mining community would immediately understand.

'They found 650,000 emails in the current investigation of somebody else,' Trump said, referring to Weiner without name-checking him.

'You know, in the diamond business and the coal business, it's called – Don't worry, we're putting your miners back to work! Clean coal! Clean Coal! – They call [it]: This could be the mother lode.'

'This could be the 33,000 that are missing!' Trump said, referring to the emails his Democratic rival has acknowledged that she ordered her lawyers to destroy.

'This could be the 20,000 that are missing. This could be the 15,000 that are missing. Three weeks ago they're missing a big box of emails.'

Trump suggested that no one person could receive and send 650,000 emails, meaning that the trove on Weiner's PC would have been collected from others' accounts

Trump seemed to suggest 650,000 emails were too many for any one person to accumulate, meaning they would have to have been collected from elsewhere.

'Think of it – 650,000!' he said. 'What do you have to do, to do 650?'

'Just, if you sat there and did like this – one, two, three – you'd be there for weeks! How can you have 650,000 emails?'

'If she'd never heard the word "email," do you think she'd be a very happy woman today?' he asked.

In Las Vegas, an exuberant Trump delivered Weiner a swift kick by thanking him for preserving the emails that could bring Clinton down.

He told more than 7,000 people packed into a casino ballroom that he believes the FBI has recovered some of Clinton's 33,000 deleted emails.

'I have a feeling they just found a lot of them,' he said, before calling out the name of Weiner's estranged wife Huma Abedin.

'Huma! They just found a lot of them!' he boomed.

A day earlier in Arizona, the real estate billionaire used the 'pervert' Weiner's proximity to power as Exhibit A in his case that the Clintons have poor judgment and can't be trusted with the levers of power.

'As Podesta said, she's got bad instincts,' he said, quoting Clinton campaign chairman John Podesta's stinging admission in a hacked email published by the WikiLeaks anti-privacy group.

'Well, she's got bad instincts when the emails are on Anthony Weiner's – wherever,' Trump quipped. 'Ooh. He's bad.'

In addition to being the long-suffering spouse of the infamous sexting Weiner, Abedin has served Clinton for decades as a key aide and is now the vice-chair of her White House campaign.

For more than a year, Trump has seeded his comments about Clinton's email scandal with loose accusations that Abedin had access to classified documents of the sort that his Democratic rival is accused of storing on an unsecured email server.

A 'pervert' like Weiner sharing Abedin's bed, he has suggested over and over, represented an unacceptable national security risk.

News reports on Friday first described a cache of Clinton-related emails found on a laptop the married couple shared.

The Clinton campaign raced to persuade reporters that there was no evidence the messages weren't duplicates of what the FBI had already reviewed when it decided not to recommend prosecution under the U.S. Espionage Act.

But Trump was merciless to Weiner, whose computers were seized in an investigation prompted by a DailyMail.com story describing his online affair with a 15-year-old girl.

'I don't know if anybody saw my comments on Anthony Weiner,' he said Saturday in Phoenix. 'I had no idea I was going to be that accurate!'

'Hillary has nobody but herself to blame for her mounting legal troubles. Her criminal action was willful, deliberate, intentional, and purposeful,' he said Sunday at the Venetian resort, owned by his friend, fellow billionaire and political donor Sheldon Adelson.

'She set up this illegal server knowing full well that her actions put our national security at risk, and put the safety and security of your children at risk.'

An emcee at the Nevada rally told his surging crowd that there was 'a fleet of black buses waiting in the valet parking area' to drive them to early voting locations.'

The Silver State's Hispanic-heavy demographics reflected on the crowd, with homemade 'Latinas for Trump' signs rivaling professionally printer 'Women for Trump' placards for space.

Midway through Trump's speech, he spotted one in the crowd and invited the Mexican-American woman holding it to come on stage.

'I'm very proud to vote for Mr. Trump because he's for law and order,' she said.

'You have to come into this country legally!'

The woman complained about illegal immigrants who reflect badly on her community and sap the U.S. treasury though benefit payments and public services.

'It costs $115 billion a year to support them' in Nevada, she said.

Trump praised her: 'She's better than me! I never did it that well!'

'We are going to do so well with the Latinos!' he yelled.

Trump's pre-show warmup acts whipped the Las Vegas crowd into a frenzy.

Right-wing radio talk show host Wayne Allyn Root drew screams of 'Lock her up!' when he promised that a conservative revolution was – figuratively – descending on America's political elites 'with pitchforks, jackhammers and blowtorches.'

'We're coming to tear it up,' he said, directing his fire at Clinton.

'We're coming to kick your ass. And we're coming to put you in prison!'

'Hillary and Huma have been done in by a leaking Weiner,' he mocked.

'Huma! They just found a lot of them! [emails]' he boomed. 'We never thought we were going to say "Thank you" to Anthony Weiner!'

Root said a recurring dream-sequence in his head consists of 'Hillary's run for the border with Huma in a white Ford Bronco,' dredging up images of O.J. Simpson's slow-speed chase with police in 1994.

Only his story has a more abrupt ending: 'When they make the run to Mexico there's nowhere to go, because President Donald J. Trump has built a big, beautiful wall!

'Pawn Stars' king Rick Harrison declared that he 'can't imagine the world with Hillary Clinton as president.'

'She really believes in the socialist paradise,' Harrison said, shaking his head as he added that socialism is 'like a really bad drug.'
