A liberal activist and organizer collaborated with the right-wing news site Breitbart on coverage of him interrupting GOP presidential primary candidates, according to a new report.

“[Black] was coordinating with [Breitbart’s] top staff to rabble rouse against Rubio at rallies,” the source said, citing various disruptions during the Florida senator's presidential campaign events.

Politico’s source said Black coordinated with Breitbart journalists via email, phone and even in-person meetings.

Black is an associate with the liberal-leaning Democracy Partners super PAC, it said, and is also a former Occupy Wall Street organizer.

Politico added Black has since conducted interviews with Breitbart and appeared on the outlet’s radio programs.

“Aaron Black reached out to Breitbart and then we covered this and multiple other stories on our website and on our radio show on Sirius XM Patriot Channel 125,” Breitbart editor-in-chief Alex Marlow told Politico in a statement Monday. “Breitbart News Network is proud to work with sources from across the political spectrum to cover important and breaking news stories so that we may bring the most informative reporting to our readers.”

"Some Democracy Partners staff worked with groups that gave voice to the majority of Americans left out of the extreme conservative agenda of the Republican Party," Democracy Partners said Tuesday in a statement to The Hill.

"The statement that Aaron Black, an Associate with our firm, 'coordinated' with Brietbart News, is incorrect," Democracy Partners added.

“In order to engage as much media coverage as possible, Black disseminated to media outlets information about the whereabouts of demonstrations and rapid response events,” the firm added.

“The coalition demonstrated against all seventeen of the Republican candidates. We engaged the media from across the political spectrum. When we organized events aimed at a Trump opponent, Breitbart was more than happy to spread the word. When we organized events against Mr. Trump, Breitbart amplified the Trump Foundation-funded con artist James O’Keefe, who attacked our firm and coalition.”

Politico said Black was the man dressed as a robot who memorably disrupted Rubio during the GOP presidential primary earlier this year.

Footage emerged in February, for example, of Rubio’s supporters tussling with Black while he was wearing the costume in New Hampshire.

Black resurfaced earlier this month, Politico added, during videos released by conservative activist James O’Keefe’s Project Veritas.

Veritas began releasing undercover footage earlier this month of Democratic operatives discussing how to instigate violence at Trump’s events.

Politico said Black details helping organize demonstrations that forced Trump to cancel a rally in Chicago last March.

Breitbart Chairman Steve Bannon, meanwhile, became Trump’s campaign CEO in August after taking a leave of absence from the conservative site.
