President Donald Trump thanked Tehran for a "very fair" negotiation that led to the release Saturday of an America scholar held in Iran and an Iranian scientist jailed in the US.
Xiyue Wang, a Princeton University researcher held for three years in Iran, was exchanged in Switzerland for Massoud Solemani, who had been arrested in Chicago more than a year ago.
In a tweet, Trump boasted that Wang was taken during the Obama administration and "returned during the Trump Administration."
"Thank you to Iran on a very fair negotiation. See, we can make a deal together!"
