Vice President Kamala Harris has emerged as one of the highest-ranking American officials urging restraint by Israeli forces.
The president attended the annual conference in 2021 and 2022, but officials say this year he is preoccupied with the wars in the Middle East and in Ukraine.
The deal came as Democrats are increasingly divided over Mr. Biden’s embrace of Israel, particularly as the civilian toll in Gaza grows.
Hamas has offered no information about the nearly 240 hostages, including children, who are said to be held in Gaza.
John Kirby, a spokesman for the National Security Council, said that intelligence from U.S.-generated sources supported Israel’s claim that Hamas has tunnels under Al-Shifa and other hospitals.
The United States is under growing pressure to use its leverage to push for sustainable, long-term goals in the region and minimize civilian casualties in Gaza.
President Biden’s team emphasized that polls have failed to predict the results of elections when taken a year ahead of time.
The goal is to help bolster economies of countries across the region so they can better absorb the millions of migrants who are fleeing poverty, political instability and natural disasters.
Brief cessations of military operations would allow food, water and other aid to reach Gaza and help with hostage releases, officials say.
The deadliest mass shooting of the year will present the president with the familiar ritual of comforting grieving families. He will likely also press his case for gun control.
