"I recently offered to travel to Tehran and speak directly to the Iranian people. The regime hasn’t accepted my offer," Pompeo wrote on Twitter.
The State Secretary stressed that Washington was not afraid of Iranian officials coming to the United States.
"We aren’t afraid of @JZarif [Iranian Foreign Minister Javad Zarif] coming to America where he enjoys the right to speak freely. Are the facts of the @khamenei_ir [Supreme leader of Iran Ali Khamenei] regime so bad he cannot let me do the same thing in Tehran? What if his people heard the truth, unfiltered, unabridged?" Pompeo added.
