Impeachment Inquiry Puts Spotlight on Perry, Who Shunned It Associated Press WASHINGTON - Long after more flamboyant colleagues flamed out of President Donald Trump's favor amid ethics scandals, low-profile and folksy Rick Perry survived in the Cabinet in part by steering clear of controversy. Until now. The former Texas governor said Thursday that he was quitting as energy secretary by year's end. The announcement came as the House impeachment investigation highlighted his work in Ukraine, where he promoted U.S. natural gas and where Trump hoped to find dirt on Democratic rival Joe Biden. Trump said that Perryhad plannedfor months to leavethe Cabinet, but the timing of the announcement of Perry's departure fits a Trump pattern, said governance expert Kathryn Dunn Tenpas of the Brookings Institution. Her work shows there has been more turnover in Trump's Cabinet than under anyotherpresident since at least Ronald Reagan. ``The more important the issue is to the president, the more likely you're on the chopping block,'' Tenpas said. No evidence has emerged that Perry explicitly pressured Ukrainian officials to comply with Trump's push to investigate a Ukraine natural gas company where Biden's son Hunter was a board member. It's a central part of the impeachment investigation. .
