Washington (CNN) President Donald Trump's personal attorney Rudy Giuliani on Sunday said he spoke last week with Secretary of State Mike Pompeo about Giuliani's meeting with a Ukrainian official, adding that Pompeo didn't direct him to have that meeting.

During an interview on CBS' "Face the Nation," the former New York City mayor said then-special US envoy to Ukraine Kurt Volker and US Ambassador to the European Union Gordon Sondland were the ones who directed him to meet with the Ukrainians. During the interview, Giuliani was asked whether Pompeo directed him to meet with the Ukrainians.

"He did not. Mr. Volker did and Mr. Sondland did. But when I talked to the secretary last week, he said he was aware of it," Giuliani told host Margaret Brennan.

A source familiar with the State Department's contact with Giuliani previously refuted that characterization, telling CNN that Giuliani's assertion that he was directed to contact Ukrainian officials by the State Department is "totally false."

Sondland has refused to comment on anything related to Giuliani. Volker has not responded to requests for comment about Giuliani's statements.
