(CNN) A reporter for National Public Radio said Friday that Secretary of State Mike Pompeo screamed obscenities and demanded she prove she could find Ukraine on an unmarked map after she asked -- and Pompeo refused to answer -- whether he owed former US Ambassador to Ukraine Marie Yovanovitch an apology.

The alleged incident took place after the taping of an interview that aired on NPR's "All Things Considered" Friday. Pompeo instead replied to NPR's Mary Louise Kelly question by saying, "You know, I agreed to come on your show today to talk about Iran. That's what I intend to do. I know what our Ukraine policy has been now for the three years of this administration."

He then repeatedly tried to end the interview as Kelly continued to press him on the matter. To her last question on whether Ukraine policy had been hijacked, Pompeo replied, "I've been clear about that. I know exactly what we were doing. I know precisely what the direction the State Department gave to our officials around the world about how to manage our Ukraine policy."

Kelly told listeners in a broadcast later on NPR that after the interview she was called back into Pompeo's living room at the State Department, where the outburst then unfolded.

"What is happening (at the end) there is an aide has stopped the interview, said, 'We're done, thank you,' and you heard me thank the secretary," Kelly said on air after the fact. "He did not reply -- he leaned in, glared at me, and then turned and with his aides left the room."
