On July 5, President Donald Trump accepted the resignation of Environmental Protection Agency chief, Scott Pruitt. The announcement came in the wake of months of ethics scandals surrounding the former EPA head, including costly trips at the expense of taxpayers and reports that he asked aides to perform personal tasks for him.

According to Trump’s announcement via Twitter, Andrew Wheeler, Pruitt's recently-Senate confirmed deputy, will "assume duties as the acting Administrator of the EPA" on Monday, July 9. Wheeler will hold the position until until the president formally announces a new agency head, as noted by the New York Times, which could keep Wheeler in the job for several months. Given that information, here is everything you should know about the new leader of the EPA:

1. Wheeler denies human-caused climate change.

Much like his predecessor, Wheeler is known for associating with people who do not believe in climate change science. During his Senate hearing in November 2017, Wheeler expressed support for President Trump and Pruitt’s “new direction” of dismantling environmental protection regulations and removing “red tape” for businesses. Despite scientific evidence that humans contribute to climate change, Wheeler maintained that “man has an impact on the climate, but what is not completely understood is what the impact is.”

During his opening statement to the Senate, Wheeler said: “the environment today is cleaner than it has ever been in modern times. As a Nation, we have made tremendous progress since the 1970s, and we have to build upon that progress going forward.”

2. Wheeler is a former coal lobbyist

According to ProPublica, Wheeler worked as a registered lobbyist for the coal company Murray Energy Corporation, which describes itself as “largest coal mining company in America.” Wheeler also worked as a paid lobbyist for Xcel Energy, Energy Fuels Resources, and Domestic Fuel Solutions Group. According to the New York Times, Wheeler’s career was built on “quietly and incrementally advancing the interests of the fossil-fuel industry” by “weakening or delaying federal regulations.”

Wheeler’s ties to coal and energy organizations have sparked criticism from Democratic lawmakers like Senator Elizabeth Warren, who remarked on Twitter that Wheeler would try to “poison the agency – and the environment he’s supposed to protect – from the inside.”

3. He worked for Senator Inhofe, who calls global warming a “hoax”

Wheeler previously worked as the chief of staff to Senator Jim Inhofe, an Oklahoma Republican who authored a book calling global warming a “conspiracy” and “hoax.” Inhofe went viral in 2015 for carrying a snowball to the Senate floor to try to disprove global warming, according to the New Republic. Many of Inhofe’s former staffers now work inside the EPA, where they continue to push the idea that environmental science is not accurate.

4. During the presidential campaign, Wheeler called Trump a “bully” with “baggage.”

In February 2016, Wheeler wrote in a now-deleted Facebook post that Trump was a “bully,” adding that “this alone should disqualify him from the White House,” according to a report from Politico. During the presidential race, Wheeler served as an environmental adviser to Senator Marco Rubio, who has also raised doubts about climate change science.

In the full Facebook post, Wheeler also remarked that “as a businessman, [Trump] really hasn't been that successful. He is a successful PR person, but not a businessman. He has more baggage then all of the other Republican candidates combined.”

5. Wheeler helped push for the largest reduction of national monuments.

According to NPR, Wheeler played a role in lobbying for the reduction of Bears Ears National Monument in Utah when he worked for a uranium mining firm. President Trump approved the boundary change in 2017, marking the largest rollback of federal land protection in the nation’s history, according to the New York Times.
