Investigative reporter Jeremy Scahill shared a startling revelation last week that Iranian negotiators had recruited psychologists to help navigate what they believed was Trump’s “impaired mental state.” And on Monday, Scahill provided an update on Iran’s unique approach to the negotiations, which he said Tehran partially credited for Sunday’s success.

“Senior Iranian psychologists began working with the negotiating team to try to cater the messages that the Iranians were sending via mediators back to Donald Trump to try to take into account what they say as his specific mental illness and mental deficiencies,” Scahill said in an interview with Democracy Now published on Monday.

“Almost quite clinically, they said they began to see this process yielding results as they worked with psychologists to send these communications to Donald Trump, and they credit that, in part, with getting to this point where Trump finally accepted some version of his manufactured and almost entirely false victory narrative.”
