"I can confirm Special Envoy Witkoff and Jared Kushner will be off to Pakistan again tomorrow morning to engage in talks," White House Press Secretary Karoline Leavitt told Fox News on Friday.

"The Iranians reached out, as the president called on them to do, and asked for this in-person conversation," she said.

"We're hopeful that it will be a productive conversation and hopefully move the ball forward towards a deal."

The talks would come more than two weeks after Vice President JD Vance held a first round of talks with Iranian representatives in Pakistan.

Vance was ready earlier this week to fly back out but put his trip on hold after Iran did not confirm participation.

Leavitt said that Vance remained ready to fly to Pakistan but will not for now.

"Everyone will be on standby to fly to Pakistan if necessary," she said.

Witkoff, a Trump business associate turned globe-trotting negotiator, and Kushner, Trump's son-in-law, had been negotiating with Iran just before Israel and the United States launched attacks on February 28, leading Tehran to accuse them of deceit.

During the first round of talks in Pakistan, Vance said that Iran refused US demands on constraints on its contested nuclear program.

Trump has indefinitely extended a ceasefire, after earlier issuing genocidal threats to destroy all Iranian civilization.

"The president always wants to give diplomacy a chance. It's always his first option, and he's willing to do that here again," Leavitt said.
