The group wants to include language backing enforcement of laws that ban giving military aid to individuals or security forces that commit gross violations of human rights.
“We’re going to make our voices heard,” said Liano Sharon, a business consultant and delegate who signed an alternative platform along with 34 other delegates. “Freedom of expression necessarily includes the right to stand up and be heard even when the authority in the room says to shut up.”
The Harris campaign declined to comment.
The party’s draft platform released in mid-July calls for “an immediate and lasting ceasefire” in the war and the release of remaining hostages taken to Gaza during an October 7, 2023 attack by Islamist militant Hamas fighters in which Israel says 1,200 people were killed.
Mediators including the US have sought to broker a truce between Israel and Hamas, which rules Gaza, based on a plan Biden put forward in May but so far have not succeeded.
The war, now in its 11th month, reduced support for Democrats among Muslim and Arab-American voters, who represent crucial votes in election battleground states such as Arizona, Michigan and Pennsylvania.
Nadia Ahmad, a law professor at Florida’s Barry University and a delegate, said there were about 60 Muslim delegates, a fraction of the 5,000 overall. But their concerns were shared by others, she said.
The Uncommitted National Movement, a separate effort pushing Democrats to change policy on Israel that won over 30 delegates in primary elections, also wants an arms embargo. But it has focused, unsuccessfully so far, on winning a main-stage speaking slot for a Palestinian American or Gaza humanitarian worker.
Late on Saturday, convention organisers added a daytime panel discussion on Arab and Palestinian issues to Monday’s agenda and one on antisemitism. Jewish Americans, traditionally Democratic voters, have voiced concern about rising anti-Jewish activity and Muslims have denounced rising American Islamophobia.
Layla Elabed, the Uncommitted National cochairwoman, Minnesota Attorney General Keith Ellison, a Muslim ally of Biden’s, and a doctor who has worked on the Gaza front lines will be speakers on the first panel, sources said.
Uncommitted, which said it is not planning to disrupt the convention proceedings, is pressing Harris to make a statement about the use of US weapons to kill Palestinians.
