Secretary of State Mike Pompeo admitted Wednesday that he participated in a White House phone call with Ukrainian leader Volodymyr Zelensky, an incident which is at the center of the impeachment inquiry into President Donald Trump.

The admission came as at least three State Department officials prepared to speak with House committees regarding the Trump administration’s relations with Ukraine and the phone call.

While visiting Rome, Pompeo told reporters, “As for was I on the phone call? I was on the phone call.” The statement contradicted his earlier indication that he knew nothing about the call.

Pompeo’s comments came amid news that the inspector general of the State Department, Steve Linick, has requested an “urgent” closed-door meeting on Wednesday with the House Oversight, Intelligence, and Foreign Affairs Committees, which subpoenaed Pompeo last week. The committees demanded documents related to the phone call by October 4 and asked for depositions from five other State Department officials. Pompeo said Tuesday that he would not obey the subpoena.

The secretary of state said the phone call was part of standard communications between the U.S. and Ukraine and was focused on the Trump administration’s support for the country. Pompeo’s deflection of questions about the appropriateness of the phone call, in which Trump asked Zelensky to find incriminating information about 2020 Democratic candidate Joe Biden’s son, represented the administration’s familiar pattern of admitting wrongdoing, one critic noted on social media.

The admission comes in stark contrast to Pompeo dodging a direct question last week about whether he knew anything about the conversation between Trump and Zelensky.
