Black has resurfaced recently as one of the people featured in undercover video from the Project Veritas group. In the video, he claims to work for the Democratic National Committee. Though he does not appear on their payroll, his bio at Democracy Partners credits him with “working closely with the Democratic National Committee” during the 2012 election cycle. Black in the video says he helped organize protests in Chicago that led to Trump’s cancellation of a rally there in March.

According to the source, Black coordinated with Breitbart via email, phone and in person, including when he dressed up as a robot and trolled Marco Rubio’s events. The relationship was described as very friendly. An article subsequently published on Breitbart featured video footage of a physical confrontation between Black and Rubio’s New Hampshire campaign chairman.

“He worked directly with Breitbart’s political team on the ground in the primary states to sabotage Marco Rubio & Ted Cruz, and elect Trump as nominee of [the Republican] party,” the source told POLITICO. “[Black] was coordinating with [Breitbart’s] top staff to rabble rouse against Rubio at rallies.”
