Washington (CNN) House Democrats on Thursday issued a subpoena to Energy Secretary Rick Perry for documents related to the Trump administration's contacts with Ukraine as part of the ongoing House impeachment inquiry.

The subpoena was issued by the House Intelligence Committee in consultation with the House Foreign Affairs and Oversight committees. It is just the latest in a series of subpoenas issued by House Democrats to administration officials and others as they investigate Trump's contacts with Ukraine in the wake of a whistleblower complaint alleging that President Donald Trump pressured the Ukrainian President to solicit interference in the 2020 election by urging him to investigate Democratic presidential candidate Joe Biden's family.

A letter sent to Perry by the House Democratic chairmen of those three committees states that "public reports have raised questions about any role you may have played in conveying or reinforcing the President's stark message to the Ukrainian President."

Last week, Perry pledged to work with lawmakers looking into the whistleblower complaint.
