The Hostages and Missing Families Forum will again lead cease-fire and hostage release demonstrations across Israel on Wednesday, according to a schedule posted to social media.

"The public is called to join and come together with the families of the abductees to the houses of the ministers and coalition members and hold demonstrations and protest vigils demanding that they exercise their authority to bring about a deal now," the Forum wrote on X.

Among the gatherings will be one outside the Jerusalem home of Strategic Affairs Minister Ron Dermer -- a former member of the dissolved war cabinet and long considered a close ally of Prime Minister Benjamin Netanyahu.

Activists plan to protest at the homes of eight other government ministers and three members of parliament, the Forum said.

Far-right National Security Minister Itamar Ben-Gvir said he is "working to stop the negotiations with Hamas," as talks over a cease-fire and hostage release deal continue under massive public and international pressure.

Ben-Gvir -- one of the most vocally hawkish members of Prime Minister Benjamin Netanyahu's government -- wrote on X that Israel should end negotiations and cut fuel and electricity to Gaza in response to Hamas' recent killing of six hostages in the southern strip.

"Continuing the negotiations only spurs them to produce more and more terror," including in the West Bank, Ben-Gvir said.

Ben-Gvir is a longstanding proponent of expanding Israeli settlements in the West Bank. He has called on the government to "encourage" Israelis to settle in Gaza while suggesting "voluntary emigration" of Palestinians from the territory.

Ben-Gvir was convicted of incitement to racism and supporting a terror organization in 2008, related to an anti-Arab placard he displayed at a protest following a Palestinian terrorist attack in Jerusalem. Signs referring to the far-right Kach movement -- a Jewish group banned as a terror organization -- were also found in his car.

Second gentleman Doug Emhoff said Tuesday night that the parents of Oct. 7 hostage Hersh Goldberg-Polin, who the Israeli military found had been killed last week, do not want their son's "death to be in vain."

Emhoff opened up about the recent conversation he and his wife, Vice President Kamala Harris, had with the couple after learning of the death of their son.

Speaking at a vigil hosted at the Adas Israel Congregation synagogue in Washington, D.C., which was organized to honor the memory of the six Israeli hostages found killed by Hamas in Gaza, Emhoff said Rachel Goldberg-Polin and Jon Polin remained committed to seeing the remaining hostages released.

"And yet, with this unspeakable tragedy that they were going through … they were comforting us, but also asking about the latest in the negotiations," Emhoff told those gathered at the vigil about the call with the grieving couple, which occurred last week. "They were asking how we can use this terrible moment to make progress on the deal. And they told the vice president, in no uncertain terms, they do not want Hersh's death to be in vain. And they spoke with such grace, such compassion, such strength. And even though part of Rachel and Jon's world had just ended, they were somehow still looking forward and looking out for others."
