Protesters have become a regular feature of Republican presidential frontrunner Donald Trump’s events, and Tuesday night’s debate proved no different.

While the protester’s exact words were unintelligible during the live broadcast, a voice shouting could distinctly be heard while Trump was responding.

CNN’s Dylan Byers identified the protester as Kai Newkirk, a member of the group 99 Rise.

A Twitter user by the same name tweeted he caused the disruption to call attention to big money in politics.
