Rochester, NY -- Video from a Donald Trump campaign rally Sunday in Rochester offers a clue about what people might expect from his rally in Syracuse on Saturday.

The Rochester rally had vendors selling everything from Trump t-shirts, hats and buttons to teddy bears. People chanting to "build the wall, build the wall," a reference to Trump's plan to have Mexico build a wall to keep illegal immigrants out of the United States. And there were Trump protesters.

The Rochester Democrat & Chronicle said 7,500 people packed an airplane hangar Sunday, while hundreds more waited outside to hear the Republican presidential front runner speak.

Protesters twice interrupted Trump's hour-long speech, and a group of protesters gathered on the road outside the building.

A video by Trump supporter Irina Gorchakov posted on Youtube shows two protesters at the rally wearing yellow cloth Stars of David and holding up a black flag with white arrows on it. Others grabbed the flag and threw it into the crowd like a game of keep away.

Protesters appear to haunt Trump campaign rallies. The Trump campaign moved a planned April 17 rally in Buffalo to April 18, the day before the primary, after The Buffalo News ran a story about protests planned for the event.

Trump is scheduled to speak in Syracuse on Saturday, but his campaign has yet to say where and when the event will take place.
