Israeli Prime Minister Benjamin Netanyahu is set to make a long-awaited White House visit Thursday to meet with President Joe Biden and likely Democratic nominee Vice President Kamala Harris at an important moment for all three politicians.

Netanyahu’s White House visit, his first since before President Donald Trump left office in 2020, comes at a time of growing pressure on all three to find an endgame to the nine-month war that’s left more than 39,000 dead in Gaza. Dozens of Israeli hostages are still languishing in Hamas captivity.

Biden is pressing to get Israel and Hamas to seal his proposal to release remaining hostages in Gaza over three phases — something that would be a legacy-affirming achievement for the 81-year-old Democrat, who abandoned his reelection bid and endorsed Harris. It could also be a boon for Harris in her bid to succeed him.

White House officials say that the negotiations are in the closing stages but there are issues that need to be resolved.

Following their midday talks, Biden and Netanyahu will meet the families of American hostages.

Harris, who will meet separately with Netanyahu later, is trying to demonstrate that she has the mettle to serve as commander in chief. She’s being scrutinized by those on the political left who say Biden hasn’t done enough to force Netanyahu to end the war and by Republicans looking to brand her as insufficient in her support for Israel.

A senior administration official, who briefed reporters on the condition of anonymity under ground rules set by the White House, said there is “no daylight between the president and vice president” on Israel. Harris’ last one-on-one engagement with Netanyahu was in March 2021, but she’s taken part in more than 20 calls between Biden and Netanyahu.

Netanyahu, meanwhile, is trying to navigate his own delicate political moment. He faces pressure from the families of hostages demanding a cease-fire agreement to bring their loved ones home and from far-right members of his governing coalition who demand he resist any deal that could keep Israeli forces from eliminating Hamas.

Netanyahu, in a fiery address before a joint session of Congress on Wednesday, offered a robust defense of Israel’s conduct during the war and lashed out against accusations by the International Criminal Court of Israeli war crimes. He made the case that Israel, in its fight against Iran-backed Hamas, was effectively keeping “Americans boots off the ground while protecting our shared interests in the Middle East.” The Israeli leader spent scant time discussing the ongoing negotiations.

“Remember this: Our enemies are your enemies,” Netanyahu told American lawmakers. “Our fight, it’s your fight. And our victory will be your victory. ”

Netanyahu used his speech to praise Biden for his administration’s support in the aftermath of the Oct. 7 attack on Israel. But Netanyahu also went out of his way to note action that Trump took during his four years in office took that benefited Israel, including recognizing Israel’s sovereignty over the Golan Heights, confronting Iran’s aggression and moving the U.S Embassy from Tel Aviv to Jerusalem. Netanyahu is set to travel to Florida on Friday to meet with Trump.

Netanyahu also slammed protesters who massed near the U.S. Capitol on Wednesday, calling them Iran’s “useful idiots.” The Secret Service beefed up security at the White House ahead of Netanyahu’s visit, erecting additional fencing and barriers near the White House campus.

Harris on Thursday said she was outraged that some protesters tagged areas near the U.S. Capitol with pro-Hamas graffiti, expressed support for the militants and burned a U.S. flag at Union Station.

“Pro-Hamas graffiti and rhetoric is abhorrent and we must not tolerate it in our nation,” Harris said in a statement. “I condemn the burning of the American flag. That flag is a symbol of our highest ideals as a nation and represents the promise of America. It should never be desecrated in that way.”

Trump and his Republican allies criticized Harris, who had events in Indiana and Texas on Wednesday, for skipping Netanyahu’s address to Congress.
