Washington (CNN) Conservative activists Candace Owens and Charlie Kirk were accosted at a Philadelphia restaurant on Monday by protesters from a local antifa group.

Owens and Kirk, who lead the conservative advocacy group Turning Point USA, had their breakfast at Green Eggs Café prematurely ended when protests erupted outside.

Owens told CNN that the protesters, who bore an antifa sticker, "immediately recognized" Kirk and her, and a much larger group approached the restaurant about 20 minutes later. She said the protesters began harassing and throwing things at Kirk and her from outside the restaurant.

Videos posted by Owens, who is black, and Kirk on Twitter depict an angry scene in which protesters recite chants such as "f--- white supremacy," "no good cops in a racist system" and "cops and Klan hand-in-hand."

Would like to personally and publicly thank the @PhillyPolice force for keeping us safe today. As you can see in the video, they were all Hispanic and black. The white liberal thugs were shouting "no good cops in a racist system".

In one video, Owens remarks to a black police officer that it is "bizarre" to her that "there are a bunch of white people saying 'no racists,' or 'no good cops,' when every single cop here is black."
