House Democrats state that Perry's dealings in Ukraine, which including pressing Ukrainian officials to have the entire board of state-owned national gas company Naftogaz replaced with a list of potential members that included Texans and Perry supporters, "raised questions about whether you were 'seeking to provide certain Americans help in gaining a foothold in the Ukrainian energy business'".
Perry's summons is being issued by the House's Permanent Select Committee on Intelligence, which carried out the order following consultations with the Committee on Foreign Affairs and the Committee on Oversight and Reform.
A nine-page letter from Rep. Adam Schiff (D-Calif.), Rep. Elijah Cummings (D-Md.) and Rep. Eliot Engel (D-NY) cites information studies that hyperlink Perry to the July 25 cellphone name by which Trump sought a Ukrainian probe into allegations that former Vice President Joseph Biden had "stopped the prosecution" in that nation of his son, Hunter.
They also sought information related to reports that Perry pressed Ukranian officials to change the management structure of a Ukrainian state-owned energy company to benefit individuals involved with an effort by Trump's attorney, Rudy Giuliani, to get Ukrainian officials to interfere in the 2020 US presidential election.
Neither the Energy Department nor the White House immediately returned requests for comment. The committees set a deadline for October 18. They reportedly helped Giuliani seek evidence of Democratic presidential candidate Joe Biden's alleged involvement in a corruption case in Ukraine.
The plan hit a snag after Zelinskiy's election, but Perry took up the effort to install a friendlier management team at the company, Naftogaz. He has denied any wrongdoing. "It's a very bad situation for our country".
The subpoena comes as two Florida businessmen tied to Giuliani and the Ukraine investigation were charged Thursday with federal campaign finance violations.
