The Senate on Monday confirmed Chris Wright, the CEO of fracking company Liberty Energy, to lead the Energy Department. 

The vote was 59-38. Democrat Sens. Michael Bennet (Colo.), Ruben Gallego (Ariz.), Maggie Hassan (N.H.), Martin Heinrich (N.M.), John Hickenlooper (Colo.), Ben Ray Luján (N.M.) and Jeanne Shaheen (N.H.) as well as independent Sen. Angus King (Maine) voted with Republicans to confirm him.

Lawmakers on both sides of the aisle indicated support for his nomination during his confirmation hearing, and he sailed out of committee on a 15-5 vote. 

“He’s a scientist who has invested his life around energy. He is indeed an unrestrained enthusiast for fossil fuels in almost every regard, but he studied nuclear,” Hickenlooper said during Wright’s confirmation hearing. “His first years of working were in solar. He has experience in wind.”

Nevertheless, Wright has also stoked some controversy over past comments downplaying climate change’s connections to extreme weather. 

However, during the hearing, he acknowledged that climate change is happening, saying it is “a global issue, it is a real issue, it is a challenging issue.”

Now that he’s confirmed, Wright will run a department that oversees energy research and loans, as well as the nation’s nuclear weapons arsenal. 

He gave significant financial contributions to Trump’s reelection campaign, giving two donations of $175,000 and $53,990 to the Trump 47 joint fundraising committee, which allocates funds to the Trump campaign, the Republican National Committee and other political committees.
