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.

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.
