Vice President JD Vance dismissed speculation that Iranian Foreign Minister Abbas Araghchi snubbed him during this weekend’s negotiations in Lucerne, Switzerland, imploring reporters to “mistrust” what they read on Iranian social media.

Vance issued the warning moments before departing Europe en route back to Washington, D.C., after the weekend’s first round of post-memorandum-of-understanding talks, during which Araghchi entered the main negotiating room before Vance arrived and left as the vice president took his seat at the table without greeting him.
