A boasting Donald Trump declared Tuesday in Colorado that the aggressive protesters who consistently turn up at his rallies have been paid large sums of money by Democrats to disrupt his campaign.

'The protesters are paid a lot of money by the DNC,' Trump said during an afternoon rally in Colorado Springs, referring to the Democratic National Committee.

'And I kept saying, "I wonder why those people are here?" Because they never seem to have much on their mind other than to stand up and protest.'

Two hours later in the western-slope city of Grand Junction, he directed his complaints at a series of live agitators whom he claimed were little more than paid actors.

His claims lean on a provocative video published Monday by the right-wing Project Veritas Action, known for capturing hidden-camera videos of liberals talking with undercover conservative operatives

As one young man held up an anti-Trump sign and boos rang out, Trump watched as he was led away from the airplane hangar where his rally took place.

'They're getting $1,500 to do that!' he claimed. '$1,500! You see how professional they are? Look at the guy!'

'Yesterday there was a story that the DNC, Democratic National Committee, is sending protesters in here, paying them $1,500 – Look at that guy! He's like a pro!' Trump marveled.

'He walked out, and by the time he got to the door it was all over,' he said, describing a workmanlike performance. 'Look at him! Look at him! Look!'

'They pay $1,500 and they give iPhones to everybody if you go in and disrupt,' the Republican nominee declared.

'This is what we're dealing with, with these people. These are bad people! And the press doesn't cover it.'

Ten minutes later two more protesters piped up on the opposite wide of the audience.

'Are they getting paid $1,500? Can you believe it?' he asked, daring his traveling press to write about it.

As a third protest broke out, this time in the section of risers behind him, Trump joked that the DNC had an irresistable sales pitch for the two protesters chanting slogans.

'Maybe I'll do it a couple of times. It's good money!' he laughed. 'I'll get a nice sweet phone.'

'I'm sure their parents are really proud of them.'

Trump's riffs about paid agitators was delivered off-the-cuff, and were not part of his prepared remarks.

The Republican presidential nominee's claim leans on a provocative video published Monday by a right-wing organization known for capturing hidden-camera videos of liberals talking with undercover conservative operatives.

That group, Project Veritas Action, released footage showing the national field director for the progressive Americans United for Change explaining how anti-Trump protesters are paid.

Hillary Clinton's campaign, Scott Foval says on video, 'pays the DNC. DNC pays Democracy Partners, Democracy Partners pays the Foval Group, the Foval Group executes the s**t on the ground.'

'It doesn't matter what the friggin' legal and ethics people say,' Foval concludes. 'We need to win this motherf*****r.'

He says his staff trains protesters 'on how to get themselves into a situation on tape, on camera, that we can use later.'

Bob Creamer, the founder of Democracy Partners, a left-wing organizing consultancy, told an undercover investigator that his organization has 'a whole team across the country that does that ... wherever Trump and Pence are gonna be.'

He said his assets on the ground include 'consultants and people from the Democratic Party, and the Democratic Party apparatus, and people from the campaign, the Clinton campaign.'

Creamer is married to Illinois Democratic Congresswoman Jan Schakowsky – and is a convicted felon. He pleaded guilty in 2005 to defrauding nine different banks and othe financial institutions of $2.3 million.

Barely a year after he was released from prison, Creamer went to work for President Barack Obama's 2008 presidential campaign, training volunteers.

Creamer's organization specifically takes credit for the largest and most violent protest of the Trump campaign, a March 11 melee in Chicago.

Trump supporters brandished placards at the rally on Tuesday

U.S. Secret Service called off the Republican candidate's downtown rally that night after agents on the ground concluded that there were credible threats to Trump's safety.

Aaron Black, a Democracy Partners organizer, said on tape: 'The Chicago protest when they shut all that? That was us. ... None of this is supposed to come back to us, because we want it coming from the people, we don’t want it to come from the party.'

The video also includes a testimonial from activist Zulema Rodriguez, who says she and Black 'did the Chicago Trump event where we shut [it] down.'

Rodriguez also takes credit for organizing a separate arizona protest that shut down the only road leading to an outdoor Trump rally site.

The Daily Caller reported Monday that the Hillary Clinton campaign paid Rodriguez more than $1,600 in 'payroll' shortly before the abortive Chicago rally.

A separate $30 expense was reported to the Federal Election Commission as a 'phone' payment.

Foval also confessed on tape that his organization has paid mentally ill and homeless people to take part in political protests.

'We have mentally ill people that we pay to do s**t, make no mistake,' he said on the Project Veritas Action video.

'Over the last twenty years. I've paid off a few homeless guys to do crazy stuff.'

'A lot of our union guys ... they'll do whatever you want,' he added.

'When I need to get something done in Arkansas, the first guy I call is the head of the AFL-CIO down there, because he will say, "What do you need?" And I will say I need a guy who will do this, this and this. And they find that guy. And that guy will be like, "Hell yeah, let's do it".'

Trump blamed reporters on Tuesday for failing to aggressively cover the Project Veritas Action video.

'It was barely covered by the media, but it's all over the Internet,' he said in Colorado Springs of the faux-protester exposé.

'They were bussed in. They were paid $1,500 each and given cell phones [and told]: "Go up and disturb Trump rallies".'
