Vice President JD Vance is considering face-to-face talks with Mohsen Rezaei, the hard-line secretary of Iran’s Supreme National Security Council, as the Trump administration seeks to revive diplomatic efforts to end the war with Iran, U.S. and Middle East officials told The Wall Street Journal.

Vance sent Rezaei a letter in October reportedly requesting a meeting, though discussions remain preliminary and no date has been set, according to the outlet. Doha, Qatar, is among the locations being considered for a potential meeting. Trump has confirmed Vance sent the letter last month, though he said it was focused on humanitarian and medical supplies.

Vance has appeared eager to reach a diplomatic agreement to end the war as he blamed the GOP’s midterm election losses on the conflict, even while Secretary of State Marco Rubio said on Tuesday that Iran’s demands to end the war are “absurd” and “not even serious.”

Iranian Foreign Minister Abbas Araghchi dismissed reports of a planned meeting on Tuesday, saying no such talks were scheduled. Rezaei also claimed the U.S. was spreading “fake news” about “imaginary talks,” and insisted that Iran “won’t remove even a single particle of enriched nuclear material from the country.”
