WASHINGTON (AP) — President Donald Trump vetoed a plan presented by Israel to the U.S. to kill Iran’s Supreme Leader Ayatollah Ali Khamenei, according to a U.S. official familiar with the matter.

The Israelis informed the Trump administration in recent days that they had developed a credible plan to kill Khamenei.

After being briefed on the plan, the White House made clear to Israeli officials that Trump was opposed to the Israelis making the move, according to the official who was not authorized to comment on the sensitive matter and spoke on the condition of anonymity.

The Trump administration is desperate to keep Israel’s military operation aimed at decapitating Iran’s nuclear program from exploding into an even more expansive conflict and saw the plan to kill Khamenei as a move that would enflame the conflict and potentially destabilize the region.

Asked about the plan during an interview on Fox News Channel’s “Special Report with Bret Baier,” Israeli Prime Minister Benjamin Netanyahu did not directly address whether the White House rejected the plan.

“But I can tell you, I think that we do what we need to do, we’ll do what we need to do. And I think the United States knows what is good for the United States,” Netanyahu said.

Netanyahu also said regime change “could certainly be the result” of the conflict “because the Iranian regime is very weak.”

Trump’s rejection of the proposal was first reported by Reuters.

Netanyahu’s office declined to comment on the reports.

Trump on Sunday issued a stark warning to Iran against retaliating on U.S. targets in the Middle East while also predicting Israel and Iran would “soon” make a deal to end their escalating conflict.

The president in an early morning social media posting said the United States “had nothing to do with the attack on Iran” as Israel and Iran traded missile attacks for the third straight day. Iran, however, has said that it would hold the U.S.—which has provided Israel with much of its deep arsenal of weaponry—for its backing of Israel.

Israel targeted Iran’s Defense Ministry headquarters in Tehran and sites it alleged were associated with Iran’s nuclear program, while Iranian missiles evaded Israeli air defenses and slammed into buildings deep inside Israel.

“If we are attacked in any way, shape or form by Iran, the full strength and might of the U.S. Armed Forces will come down on you at levels never seen before,” Trump said.

Hours later Trump took to social media again to predict “Iran and Israel should make a deal, and will make a deal.”

The U.S. president said he has a track record for de-escalating conflicts, and that he would get Israel and Iran to cease hostilities “just like I got India and Pakistan to make” after the two countries’ recent cross-border confrontation.

India struck targets inside Pakistan after militants in April massacred 26 tourists in Indian-controlled Kashmir. Pakistan has denied any links to the attackers. Following India’s strikes in Pakistan, the two sides exchanged heavy fire along their de facto borders, followed by missile and drone strikes into each other’s territories, mainly targeting military installations and airbases.

It was the most serious confrontation in decades between the countries. Trump on Sunday repeated his claim, disputed by India, that the two sides agreed to a ceasefire after he had offered to help both nations with trade if they agreed to de-escalate.

Trump also pointed to efforts by his administration during his first term to mediate disputes between Serbia and Kosovo and Egypt and Ethiopia.

“Likewise, we will have PEACE, soon, between Israel and Iran!” Trump said. “Many calls and meetings now taking place. I do a lot, and never get credit for anything, but that’s OK, the PEOPLE understand. MAKE THE MIDDLE EAST GREAT AGAIN!”

The growing conflict between Israel and Iran is testing Trump who ran on a promise to quickly end the brutal wars in Gaza and Ukraine and build a foreign policy that more broadly favors steering clear of foreign conflicts.

Trump has struggled to find an endgame to the wars in Ukraine and Gaza.

And after criticizing President Joe Biden during last year’s campaign for preventing Israel from carrying out strikes on Iranian nuclear sites, Trump found himself making the case to the Israelis to give diplomacy a chance.

His administration’s push on Tehran to give up its nuclear program came after the U.S. and other world powers in 2015 reached a long-term, comprehensive nuclear agreement that limited Tehran’s enrichment of uranium in exchange for the lifting of economic sanctions.

Trump spoke with Russian President Vladimir Putin on Saturday about the growing Israel-Iran conflict. And Trump is set to travel later Sunday to Canada for Group of Seven leaders summit where the Mideast crisis will loom large over his talks with the leaders of Britain, Canada, France, Germany, Italy, and Japan and the European Union.

Some influential backers of Trump are him urging to keep the U.S. out of Israel’s escalating conflict with Iran.

GOP Georgia Rep. Marjorie Taylor Greene, Turning Point USA founder Charlie Kirk, former Fox News host Tucker Carlson are among the prominent backers of Trump who have argued voters backed Trump because he would not involve the nation in foreign conflicts.

Kirk said last week that before Israel launched the strikes on Iran that he was concerned the situation could lead to “a massive schism in MAGA and potentially disrupt our momentum and our insanely successful Presidency.”

GOP Kentucky Sen. Rand Paul praised Trump for having shown restraint and said he hoped the president’s “instincts will prevail.”

“So, I think it’s going to be very hard to come out of this and have a negotiated settlement,” Paul said in an appearance on NBC’s “Meet the Press.” ”I see more war and more carnage. And it’s not the U.S.’s job to be involved in this war.”

In an interview aired on CBS’ “Face the Nation” GOP South Carolina Sen. Lindsey Graham said he preferred diplomatic efforts, but if diplomacy doesn’t work Trump should “go all in” on destroying Iran’s nuclear program.

“If that means providing bombs, provide bombs,” he said. “If that means flying with Israel, fly with Israel.”
