WASHINGTON (AP) — Israeli Prime Minister Benjamin Netanyahu will try to bolster U.S. support for his country's fight against Hamas and other Iran-backed militants in a speech before Congress on Wednesday even as many Democratic lawmakers plan to boycott his appearance and protesters amass around the Capitol to condemn the brutal war in Gaza and the humanitarian crisis it has created.

Netanyahu also wants to project the image of a respected statesman for an increasingly critical audience back in Israel, but that task is complicated by Americans’ divided views on Israel and the war, which has emerged as a key issue in the U.S. presidential election.

Tall steel barriers ringed entrances to the Capitol complex Wednesday, and security officers were deployed on foot, bicycle and with dogs. Overnight, hundreds of anti-war protesters organized by a Jewish group staged a sit-in at a congressional office building, crying, “Not in our name.”

Inside the Capitol, Netanyahu is assured a warm welcome from Republican lawmakers who arranged his speech in the House chamber, an appearance making him the first foreign leader to address a joint meeting of Congress four times, surpassing Winston Churchill.

Some leading Democrats and political independent Bernie Sanders plan to boycott Netanyahu's appearance. But the most notable absence will be Vice President Kamala Harris, who serves as president of the Senate and traditionally would sit behind whatever dignitary is speaking. She said a long-scheduled trip will keep her away.

The next Democrat in line, Sen. Patty Murray of Washington, is declining to attend, and former House Speaker Nancy Pelosi said she would be meeting with families of Israeli victims of Hamas instead.

Republicans targeted the absence of Harris, the new Democratic front-runner for the presidency, as a sign of disloyalty to an ally. But former President Donald Trump's running mate, JD Vance, said campaigning would also make him a no-show for the Israeli leader's speech.

Outside the Capitol, large protests are expected over the deaths of more than 39,000 Palestinians and over Netanyahu's inability to free Israeli and American hostages taken by Hamas and other militants during the Oct. 7 attack that sparked the war.

In anticipation, House Speaker Mike Johnson warned of a “zero-tolerance policy” for any signs of disturbances in the Capitol building. “It is our tradition to acknowledge every guest speaker’s right to free expression even if we disagree with their viewpoint,” the Louisiana Republican wrote to members Tuesday.

Johnson arranged the address, an honor that marks both the two countries’ historically warm bonds and the political weight that support for Israel has long carried in U.S. politics. But the attention for the visit has been diminished some by American political turmoil of recent weeks, including the assassination attempt against Trump and President Joe Biden’s decision not to seek another term.

Many Democrats who support Israel but have been critical of Netanyahu see the address as a Republican effort to cast itself as the party most loyal to Israel and to provide the prime minister with a much-needed political reprieve.

“I don’t know all the motivations for Speaker Johnson initiating the invitation but clearly he wanted to throw a political lifeline to Netanyahu whose popularity is very low in Israel right now,” Sen. Chris Van Hollen, among the dozens of Democrats set to boycott, said Tuesday.

Still, many Democrats plan to attend the address despite their criticism of Netanyahu, including Senate Majority Leader Chuck Schumer, who called for new elections in Israel in a March floor speech. Schumer, of New York, said then that Netanyahu has “lost his way” and is an obstacle to peace in the region amid the humanitarian crisis in Gaza.

Netanyahu also is to meet with Biden and Harris on Thursday, and Trump at Mar-a-Lago on Friday.

The United States is Israel's most important ally, arms supplier and source of military aid. Netanyahu's visit is his first abroad since the war started, and comes under the shadow of arrest warrants sought against him by the International Criminal Court over alleged Israel war crimes against Palestinians. The United States does not recognize the ICC.

The Biden administration says it wants to see Netanyahu focus his visit on helping it complete a deal for a cease-fire and hostage-release. Growing numbers of Israelis accuse Netanyahu of prolonging the war in order to avoid a likely fall from power whenever the conflict ends.

Netanyahu says his aims for the U.S. visit are to press for freeing hostages held by Hamas and other militants in Gaza, to build support for continuing Israel's battle against the group, and to argue for continuing to confront Hezbollah in Lebanon and other Iranian-allied groups in the region. The U.S., France and others are seeking to calm border fighting between Hezbollah and Israel, fearing a larger war.

Netanyahu in his speech also may address a new China-brokered deal between Palestinian factions Hamas and Fatah to form a government together. The agreement was an attempt to resolve a rivalry that could make it even harder for Palestinians to secure a role governing Gaza whenever the war ends. Israel immediately denounced the pact, and State Department spokesman Matthew Miller called Hamas a terror group that should have no role in governing Palestinians.

Some Democrats are wary about Netanyahu, who used a 2015 joint address to Congress to denounce then-President Barack Obama's pending nuclear deal with Iran. National Security Adviser Jake Sullivan has said he does not expect Wednesday's speech to be a repeat of 2015's.

As the prime minister speaks, multiple protests are planned in and around the Capitol. The largest is set for Wednesday morning, with organizers planning to march around the Capitol demanding Netanyahu’s arrest on war crimes charges. Relatives of Israeli hostages are planning a vigil on the National Mall.
