A group of protesters led by a man who identified himself as the head of the Maricopa County Young Democrats attempted to disrupt Donald Trump’s rally in Phoenix Arizona on Saturday.

The group of about 30 young protesters held up a banner and chanted, before being led out of the Phoenix Civic Center by security.

A leader of the group dressed in a suit identified himself to Breitbart News as The head of the Maricopa County Young Democrats, as the group was ejected. Other members of the group did not answer when asked who they were with, and some appeared not to speak English.

The crowd watching Trump’s speech immediately responded to the protest with shouts of “USA! USA!”
