One day after a contentious interview that was followed by an expletive-filled verbal lashing of NPR host Mary Louise Kelly, Secretary of State Mike Pompeo is publicly accusing her of lying to him — "twice."

In a statement released by the State Department on Saturday, Pompeo says Kelly first lied "in setting up our interview."

He does not explain how and offers no evidence. In their recorded interview from Friday, the nation's top diplomat declined to respond when Kelly asked whether he owed an apology to Marie Yovanovitch, the former U.S. ambassador to Ukraine. She was ousted from that post last year after allies of President Trump accused her of disloyalty.

"I agreed to come on your show today," Pompeo replied, "to talk about Iran."

Kelly pushed back, telling Pompeo, "I confirmed with your staff last night that I would talk about Iran and Ukraine." She later said she specifically flagged her intention to do so in writing, noting, "I never agree to take any topics off the table."
