As the issues from the stage turn to the Israeli-Hamas war, signs saying "We are Jews for Trump" are emerging from the crowd on the floor.
An Israeli flag is being waved near a woman holding a sign that says, "Free hostages, Support Israel and Fight Antisemitism."
The Biden administration has steadfastly supported Israel despite major protests from within the Democratic party's own ranks. Biden visited Israel shortly after the Oct. 7, 2023, Hamas attacks and hugged Israeli Prime Minister Benjamin Netanyahu.
Biden has rejected demands to halt all weapons shipments to Israel, although it did suspend the transfer of 2,000-pound bombs over fears they might be used in heavily populated areas in Gaza.
At the same time, US officials have been working since October to try and arrange a cease-fire agreement between Israel and Hamas that would see the release of hostages and at least a temporary end to hostilities.
Top Biden aides, including national security adviser Jake Sullivan and Secretary of State Antony Blinken, have met repeatedly with the families of American and other hostages still held by Hamas and pledged to work for their release.
The crowd chanted "Bring them home" as the parents of Omer Neutra, an American-Israeli hostage in Gaza who was kidnapped on Oct. 7, walked out onto the convention stage.
"He turned 22 on Oct. 14, 2023, and instead of celebrating with us and with his friends, he spent his birthday as a hostage of Hamas terrorists," his mother, Orna Neutra, said. "Imagine, over nine months not knowing whether your son is alive, waking up every morning praying that he, too, is still waking up every morning, that he is strong and is surviving."
Orna and her husband, Ronen Neutra, wore shirts emblazoned with their son's face on it.
"During the brutal October attack on Israel, over 1,200 people, of them, 45 were American citizens. Where's the outrage? Where is it?" Ronen Neutra asked the crowd.
"Right here," some in the crowd yelled.
"This is not merely an attack on Israel. This was and remains an attack on Americans," Ronen Neutra said.
Shabbos Kestenbaum, an Orthodox Jewish Harvard student who is suing the school over its handling of the anti-Israel protests, slammed the far-left, contending they have "not only abandoned the Jewish people, but the American people."
Kestenbaum talked about the harassment he has experienced on campus and the lack of accountability from school leaders.
"I found myself immersed in a culture that is anti-western, that is anti-American and that is anti-Semitic," he claimed.
Kestenbaum pushed people to vote for Trump arguing his policies would "expel foreign students who violate our laws, harass our Jewish class mates and desecrate our freedom."
University of North Carolina at Chapel Hill fraternity brothers, who helped protect the American flag after it was briefly replaced with a Palestinian flag during protests on the campus in April, also appeared at the convention.
