Thousands gather in Washington to demonstrate in support of Israel

Thousands of demonstrators from across the country gathered in Washington on Tuesday to support Israel amid the war with Hamas in the Gaza Strip.

Amid security concerns, the National Guard assisted local police to ensure safety around the event.

Tovah Feldshuh, an actress known for her portrayal of former Israeli Prime Minister Golda Meir, referenced the Jewish traditions surrounding death to express her grief over the Israelis killed in the fighting or taken hostage by Hamas terrorists.

"I stand here for the kidnapped babies and the Holocaust survivors abducted and hidden somewhere in Gaza. We stand here together as the yahrtzeit candles for over 1,400 slaughtered in the sovereign state of Israel only because they were Jews," she said. In the Jewish faith, a yahrtzeit candle is lit to mark the anniversary of a death.

Attendees described a difficult time since Hamas' Oct. 7 attack.

"It's been a roller coaster of emotions. Everyone's stepping up. Everyone's hanging signs of hostages, doing whatever they can to help: Sending updates, calling senators, calling policymakers, which is important, advocating what we're doing today. Everyone's life's been turned upside down because we feel for our brothers and sisters in Israel," said Micah Cyrulnik, a high school student from New Jersey.

"We've got to find resilience as a community. We'll have a lot more work to do in the weeks and months ahead. It's going to be a tough period for all of us. We're going to have to pull through for each other," added Tyler Gregory, the CEO of Jewish Community Relations Council Bay Area.

Prior to the rally, lawmakers were shown videos of Hamas' surprise Oct. 7 terror attack on Israel, which killed about 1,200 people, mostly in southern Israel near the Gaza Strip, according to Israeli officials. Speaker Mike Johnson said in his remarks at the rally on Tuesday that the lawmakers "wept as we watched the film together. Most couldn't sit through it." Israel retaliated with a bombing campaign and total siege of the Gaza Strip, leaving the region on the verge of all-out war.

A bipartisan slate of lawmakers who addressed the crowd called for the release of hostages.

"We will continue fighting for the release of all hostages 'til they return to safety," vowed Senate Majority Leader Chuck Schumer, who then led the crowd in chants of "Let them go!" and "Bring them home!"

House Minority Leader Hakeem Jeffries said, "There's a question on the minds of many of us: Where do we go from here?"

"We must stand with Israel in its effort to decisively defeat Hamas and make sure that this brutal terrorist regime can never rise again. We must make sure that every single hostage is returned home safely, and then we must stand together to ensure a just and lasting peace between Israel and the Palestinian people," he said.

Sen. Joni Ernst, while calling for the "complete and total destruction" of Hamas, vowed the United States will not "shrink back and shudder in fear."

"The brutal reality of Hamas cannot be diminished. They murder babies. They rape women. They abuse the elderly. They killed 30 of our fellow Americans, hundreds of our Israeli friends, and are currently, right now, holding 200 innocent men, women, and children hostage," she said.

Upon the conclusion of Ernst's remarks, Schumer joined hands with Ernst and Jeffries, who then grabbed Johnson by the hand, and led a chant of "We stand with Israel! We stand with Israel!"

Politically, the conflict has particularly torn open divisions in the Democratic Party between staunch Israel supporters who back Israel's military campaign to defeat Hamas, which the U.S. has designated a terrorist group, and progressives who are advocating for a cease-fire to the devastating fighting, which has caused an unfolding humanitarian crisis in Gaza.

Aid to Israel is not anticipated to be included in a short-term government funding bill Congress will soon consider.

The ensuing war after the Oct. 7 attack has killed over 11,200 Palestinians in the Gaza Strip, according to the Hamas-run Gaza Health Ministry, and 180 in the West Bank, according to the Palestinian Ministry of Health.

On Nov. 5, thousands of pro-Palestinian protesters came together in Washington to call for a cease-fire and an end to the siege on the Gaza Strip.

Growing concerns are mounting over the Al-Shifa Hospital in Gaza, which is running extremely low on resources and where Israel claims Hamas is running a command center.

President Joe Biden sounded an optimistic note earlier Tuesday about the prospect of getting some of the hostages out of the Gaza Strip, despite the fighting rendering the transportation of aid difficult.

"I've been talking with people involved every single day. I believe it's going to happen, but I don't want to get into detail," the president told reporters.

When asked about his message to the hostages' families, he responded, "Hang in there. We're coming."

The "March for Israel" -- a rally on the National Mall rather than a march -- was organized by the Jewish Federations of North America. A permit filed with the National Park Service said the organizers expected to bring up to 60,000 people to Washington to "show solidarity and support for Israel and the Israeli People."
