Energy Secretary Rick Perry talked to President Donald Trump’s lawyer Rudy Giuliani this spring at Trump’s behest to address concerns the president had over Ukrainian corruption, the former Texas governor told The Wall Street Journal.

Perry told the Journal he contacted Giuliani, the former New York City mayor, to get Trump and new Ukraine president Volodymyr Zelenskiy to meet. Perry said Giuliani relayed concerns over unsubstantiated claims about Ukraine interference in the 2016 elections.

There were not specific requests by Trump, Giuliani or anyone else in the Trump administration to talk about an investigation of former Vice President Joe Biden and his son Hunter Biden. A July 25 phone call from Trump to Zelenskiy is the basis of the impeachment inquiry in the House.

Giuliani confirmed the call to Perry in an interview with the Journal, telling him to “be careful” with the new president.

The Journal’s report comes after a trio of House Democratic committee chairmen issued a subpoena to Perry last week, giving him just over a week to produce documents related to his role in the Ukraine controversy.

The demand marked the most aggressive action toward Perry yet as House Democrats pursue the formal impeachment inquiry against Trump over allegations that Trump abused his office by pressuring Ukraine to investigate one of his political rivals.

Perry has not been accused of wrongdoing. But he’s come under an intensifying spotlight over his extensive interactions with Ukrainian officials. Perry has admitted that he asked Trump “multiple times” to call Zelenskiy — just not about former Biden, the fraught topic that was ultimately discussed on the July phone call between the two world leaders.

“Absolutely, I asked the president multiple times: ‘Mr. President, we think it is in the United States’ and in Ukraine’s best interest that you and the president of Ukraine have conversations and discuss the options that are there,'" he said, adding that his request dealt with energy.

Then Perry had to parry news reports that said he urged Ukrainian officials to put two Texas businessmen on the supervisory board of Naftogaz, a state-owned energy company, explaining that he was merely making recommendations of subject-matter experts at the request of the Ukrainian government.

Among the topics or events covered by the document request are Trump’s call with Zelenskiy, all meetings and discussions about Ukraine between Perry and Giuliani, and a host of issues related to Naftogaz.
