According to the publication, such a decision was made by the minister himself.
As specified, Perry did not associate his resignation with the talks between US and Ukrainian leaders Donald Trump and Vladimir Zelensky in July.
Earlier, Bloomberg, citing two sources, said that Perry notified Trump of his intention to resign soon.
In early October, Trump said that he did not intend to have a telephone conversation with Zelensky in July, but Perry insisted on negotiations, who advised the president to discuss “something about the liquefied natural gas plant” with the Ukrainian leader.
