Iran live updates: US blockade of Iran's Strait of Hormuz ports to begin Monday

The trilateral in-person negotiations between the U.S, Iran and Pakistan have continued into the early morning hours, according to the White House.

Asked about the state of ongoing negotiations being led by Vice President JD Vance, a senior White House official told ABC News: "15 hours and counting!"

The statement came shortly after 7:30 p.m. ET, which is 4:30 a.m. in Islamabad where the talks are taking place.

Both sides met first with Pakistani leaders before the historic sitdown Saturday, the highest level face-to-face meeting between the U.S. and Iran in 47 years.

In addition to Vance, special envoy Steve Witkoff and the president's son-in-law, Jared Kushner took part in the talks with top Iranian officials, including the speaker of the Iranian Parliament.

Speaking to reporters at the White House before leaving for Miami, President Donald Trump said he doesn't "care" what happens with Iran negotiations because "regardless what happens, we win."

"Whether we make a deal or not makes no difference to me," Trump said.

Throughout the gaggle, Trump repeatedly asserted that the United States emerges victorious, no matter the result of the ongoing negotiations in Islamabad, Pakistan.

"We'll see what happens. Look, regardless we win. Regardless what happens, we win. We totally defeated that country. And so let's see what happens. Maybe they make a deal. Maybe they don't. From the standpoint of America, we win," Trump said.

While claiming that the U.S. will open the Strait of Hormuz, the president repeated his usual criticism against other countries for their lack of assistance with the critical waterway.

"Now all we do is we'll open up the strait even though we don't use it, because we have a lot of other countries in the world that do use it, that are either afraid or weak or cheap," he said.

Asked about Iran's assets, which is a key point in the Iranian's proposal, the president sidestepped and said the U.S. is in "very deep negotiations with Iran" before repeating the assertions that the U.S. will "win regardless."

The president also repeated his claims from this morning that other countries are sending oil tankers to the U.S. to be filled with oil and gas, calling this a "beautiful thing."

"One of the things that's happening is that boats are sailing up and heading out to our country - big, beautiful tankers, and we're loading them up with oil and gas and everything else and it's pretty, beautiful thing to see," he said.

Trump also acknowledged that Iran "probably [has] a couple of mines" in the Strait of Hormuz but emphasized that the U.S. has minesweepers to combat this.

"They probably have a couple of mines in the water. We have mine sweepers out there. We're sweeping these straight. In addition to that, we're negotiating," Trump said.

The White House confirmed that trilateral meetings between the U.S., Iran and Pakistan are ongoing on Saturday.

"Trilateral in-person negotiations are ongoing," a senior White House official said in a statement to ABC News.

The "core" U.S. delegation includes Vice President JD Vance, U.S. Special Envoy Steve Witkoff and the president's son-in-law Jared Kushner, per the press pool traveling with the vice president.

Dr. Andrew Baker, deputy national security adviser to the president and national security adviser to the vice president, and Michael Vance, special advisor to the vice president for Asian affairs, will also be in attendance as the broader U.S. delegation, according to a U.S. official.

"A full suite of U.S. experts on relevant subject areas are present in Islamabad. Additional experts are supporting from Washington," the U.S. official said, per the pool.

Trump was asked if he believes the Iranians are negotiating in good faith, responding: "I'll let you know that in a very short period of time, won't take long."

The president was also asked whether or not he is hopeful about the outcome of the talks, to which he replied "whatever," and reiterated his previous statements about the U.S. military being able to "reset."

"Whatever, otherwise we'll reset. We're ready to go," Trump reportedly said.

Two U.S. Navy destroyers transited the Strait of Hormuz on Saturday in what appears to be a first since the war began, according to U.S. Central Command.

CENTCOM confirmed President Donald Trump's announcement that the U.S. military had begun mine-clearing operations to ensure safe passage through the strait.

The USS Frank E. Peterson and USS Michael Murphy "conducted operations" as part of "a broader mission to ensure the strait is fully clear of sea mines previously laid by Iran's Islamic Revolutionary Guards Corps," according to the statement. Additional U.S. forces -- including underwater drones -- will join mine-clearing operations "in the coming days," according to CENTCOM.

"Today, we began the process of establishing a new passage and we will share this safe pathway with the maritime industry soon to encourage the free flow of commerce," said Adm. Brad Cooper, commander of CENTCOM.

Defense Secretary Pete Hegseth also confirmed the ships' movement in a post on X.

"USS Frank E. Peterson (DDG 121) and USS Michael Murphy (DDG 112) transited the Strait of Hormuz and operated in the Arabian Gulf as part of a broader mission to ensure the strait is fully clear of sea mines previously laid by Iran's Islamic Revolutionary Guards Corps," Hegseth wrote.

Iran denies claims that US vessels entered Strait of Hormuz

A spokesperson for Iran's joint military command denied a claim by the United States that two Navy destroyers transited the Strait of Hormuz, saying "the initiative for the passage and movement of any vessel is in the hands of the Armed Forces of the Islamic Republic of Iran," according to Iranian state broadcaster IRIB.
