Republican presidential front-runner Donald Trump accused Hillary Clinton Friday of being responsible for the refugee crisis that led “hundreds of thousands or maybe millions” of Syrians and Iraqis to flee their homes.

“And she calls me dangerous?” Trump said, recalling Clinton’s secretary of state tenure, during a closed-door Pennsylvania Republican Party event at the Plaza Hotel, according to attendees.

Trump didn’t mention his proposal to temporarily bar Muslim refugees from entering the US.

Protesters who crashed the event interrupted his speech three times to blast the proposal. Some even paid the $1,000 entry fee to gain access.

“Maybe you should charge higher prices for these events,” Trump said of the interruptions.

“Trump is creating violence in our community,” said protester Jamila Manmani of the Responsible Endowment Coalition, who said security personnel threw him to the ground before he was forced to leave.
