The US energy chief said on Tuesday he welcomes any potential investigations by Democratic lawmakers, who will take control of congressional committees next year, into Trump administration activities in the energy sector.
"We're extremely proud of everything we've done at the (Energy Department) to advance President Trump's energy agenda," Energy Secretary Chris Wright told reporters in New Orleans.
"Happy for any investigations. And we're happy to explain everything we've done."
Democrats win US Congress in midterm elections
Democrats won control of both chambers of Congress in this month's midterm elections, giving them the power to launch investigations and subpoena Trump administration members to testify before committees.
Early this year US Representative Robert Garcia, the top Democrat on the House Oversight Committee, asked the Energy Department and other departments for information about their roles in managing Venezuelan oil revenue after the US captured the country's leader.
Democrats have also said they will probe Trump's rollbacks of policies to boost clean energy.
