"Israel's" negotiating delegation will postpone its departure and not head to Qatar tomorrow, an Israeli source revealed.

According to the source, the delay is caused by US President Joe Biden and Israeli Prime Minister Benjamin Netanyahu's meeting being rescheduled for this Thursday.

Netanyahu plans to talk with Biden about the deal to decide how to move forward, the source added.

After the meeting, the source said the delegation will leave for negotiations, without specifying when. The group may not depart until next week, according to the Walla news website.

The insider stressed that talks between the negotiators and the mediators are ongoing despite the delay.

In response, families of the captives expressed outrage during a protest march from Dizengoff Square to the Hostages Square, where they plan to watch Netanyahu’s address at Congress, followed by a rally.

Netanyahu has already arrived at Congress, where he was received by Republican Speaker of the House of Representatives, Mike Johnson.

On Wednesday, the same day Netanyahu will speak, he made headlines in Haaretz, which held him accountable for the fate of Israeli occupation captives being held by the Palestinian Resistance in the Gaza Strip.

The Israeli newspaper stated that he would be responsible for their death if he did not finalize an agreement with the Resistance.

Haaretz argued that Netanyahu is "knowingly distorting the truth" when he claims that "the prisoners are suffering but not dying." The newspaper proclaimed that the "bitter truth" was that the captives "are suffering and some of them are dying, and if no agreement is reached, they will continue to suffer and die."

According to sources and public statements reviewed by CNN, approximately 80 House Democrats and at least six Democratic senators are expected to skip Netanyahu’s speech on Wednesday.

Netanyahu is set to meet with US President Joe Biden on Thursday at the White House, according to a US official on Monday.

Reportedly, Netanyahu will be meeting with Biden and Vice President Kamala Harris separately. Talks with Biden are expected to touch on the war on Palestine where the two leaders will discuss ways to reach a ceasefire in Palestine's Gaza Strip, with topics set to include Iran and others.

Senate Majority Whip Dick Durbin of Illinois and Rep. James Clyburn of South Carolina are among the Democrats who will not attend the event. Progressives such as Rep. Ilhan Omar, D-Minn., and Sen. Elizabeth Warren, D-Mass., as well as numerous Jewish members of Congress, including Sens. Bernie Sanders, I-Vt., and Brian Schatz, D-Hawaii, will not attend the event. Those preferring to boycott are angered by "Israel's" onslaught in Gaza and the humanitarian catastrophe caused by the aggression on the Strip.
