JD Vance was supposed to be spending the week promoting his new book, the kind of event a potential presidential candidate like the vice president typically uses to speak to a wide audience about his life and values ahead of a campaign.

Instead, the rollout of Vance's second book, "Communion: Finding My Way Back to Faith," has been largely crowded out by something else he's put his name on: the tentative deal to end the Iran war.

U.S. President Donald Trump has said Washington "did send a copy" of its accord with Iran to end the Middle East war, following reports of tensions with Prime Minister Benjamin Netanyahu.

Insisting he maintains a good relationship with Netanyahu, Trump reaffirmed his criticism at the G7 summit of Israel's campaign against Hezbollah in Lebanon, saying "they (Israel) could do a much better job".

President Donald Trump signed an agreement with Iran on Wednesday that calls for Tehran to dilute its stockpile of highly enriched uranium and waives U.S.-backed sanctions on the country, immediately allowing Iran to sell its oil freely in a major concession from Washington, according to details released by both countries.

The initial deal to end the war takes "immediate effect" after leaders from both countries signed it, Pakistani Prime Minister Shehbaz Sharif, who helped mediate the agreement, said online.

Below is the full text of the U.S.-Iran memorandum of understanding, as delivered by a senior U.S. administration official in a briefing with reporters:

An Iranian official on Wednesday said the funeral procession for late supreme leader Ayatollah Ali Khamenei, who was killed by U.S.-Israeli strikes in February, will pass through Iraq before his burial in Iran.

U.S. President Donald Trump said Wednesday he expected the accord with Iran ending the Middle East war to be signed "shortly" but cast uncertainty over the exact date.

Tehran's foreign ministry on Wednesday said it was considering a plan for the presidents of the U.S. and Iran to sign the deal ending the Middle East war, ahead of the expected ceremony in Switzerland.

U.S. President Donald Trump on Wednesday warned Iran he was ready to resume military action if Tehran did not abide by its obligations, two days ahead of the signing of an accord to end the war between the foes.

"If they (the Iranian side) don't behave, we'll go right back to dropping bombs right smack in the middle of their head," Trump said at the G7 summit alongside Egyptian President Abdel Fattah al-Sisi.

Moscow supports a deal between the United States and Iran to end the Middle East war, Russian Foreign Minister Sergei Lavrov told his Iranian counterpart during a phone call on Wednesday, insisting that Israel must also comply.

"The Russian minister expressed support for the understandings reached through effective mediation by Pakistan and Qatar to de-escalate tensions in the region. The importance of compliance by all parties involved in the armed conflict, including Israel, was emphasized," the Russian foreign ministry said in a read-out of the call.

Israeli Prime Minister Benjamin Netanyahu told President Donald Trump last year that he was the "greatest friend Israel ever had in the White House."

Now, as Trump tries to finalize a deal to end the war with Iran, he's unloading on Netanyahu with rhetoric that no other American leader has dared to use publicly.
