Sen. Marco Rubio was repeatedly interrupted by hecklers Saturday morning yelling “undocumented and unafraid” in protest of the Florida Republican’s stance on immigration.

As Rubio tried to discuss anti-poverty policies at the Kemp Forum, groups of protesters yelled at intervals before they were escorted out by law enforcement. The protests, which took place over about 20 minutes, appeared to be focused on Rubio’s support for cracking down on some immigration laws.
