A female protester was violently shoved to the ground by two large male security guards at a Trump event Friday, according to video posted by PennLive.

*The woman, who identified herself in an email to Raw Story as Jamila Hammami, Arab Muslimah and executive director of the Queer Detainee Empowerment Project, was a key protest organizer and accompanied the activists that interrupted Trump to a $1,000-a-head Republican fundraiser at the Park Plaza in Pennsylvania. Video from the event shows two large men in dark suits getting physical with at least three protesters, and throwing the woman to the ground.

The woman can be heard shouting, "Stop it!" and "What is wrong with you? No, no that's not appropriate behavior!" She was helped to her feet by a fellow protester.

While protesters also gathered outside the event, some bought tickets so they could go inside, like Columbia University professor Jennifer Hirsch, who represented the advocacy group Jews for Racial Justice.

"I'm proud to be a Jew speaking out against Islamophobia," she told PennLive.

"Trump is exploiting a racial divide," Zakarariah Kronemer, who is of Egyptian descent, told PennLive. "It's leading to violence in the Arab community [in America]. The people must interrupt him anywhere he is invited to speak."

Violence at Trump rallies seems to be becoming commonplace. Last month, white Trump supporters attacked a Black Lives Matter activist at an event in Birmingham, Alabama. In October, Trump supporters knocked down and dragged a Latino protester in Florida.

Trump's speeches have been regularly punctuated by protesters angry over his racist rhetoric targeting Muslims and Latinos. This week, he was roundly criticized for saying all Muslims should be barred from traveling to the United States. He launched his campaign by saying Mexicans are rapists and drug runners.

Protesters who were inside the event and able to listen to some of Trump's speech Friday said the GOP front runner called for Bowe Bergdahl, a U.S. Army soldier who was taken captive in Afghanistan and charged with deserting, to be shot.

Trump has never served in the military.
