President Trump has threatened to veto the Keystone Pipeline and other energy projects, arguing that the project would be too costly for the U.S. and would make the country dependent on foreign oil.
The pipeline would carry crude from Alberta, Canada, to the Gulf Coast and be built on private lands.
A number of Republican senators, led by Majority Leader Mitch McConnell, have expressed opposition to the pipeline.
But Trump, who is currently in Washington for a state visit, has said he has confidence in the Environmental Protection Agency and that the president should not veto it.
“The president has tremendous respect for the EPA, and I believe they should be allowed to do what they do,” Trump said in an interview with CBS News’ “Face the Nation” last month.
“It’s a great agency, I like them very much, and they have tremendous credibility.
And they should not be blocked.”
A statement from the White House on Wednesday said that “the president does not support the Keystone project, and has repeatedly expressed his belief that the United States should not build the pipeline, despite the fact that this project would have a devastating impact on American workers and the environment.”
The president, however, has been reluctant to veto energy projects that do not directly impact his policies.
In 2015, he blocked the Dakota Access Pipeline because of concerns about its potential impact on the Standing Rock Sioux Tribe’s water supply.
Last year, he said that he wanted to build the Keystone, but did not want to put his own approval of the project at risk.
“We need to build something that’s going to be good for the American people, but I think there are going to have to be conditions put on it,” Trump told reporters at the time.
The president has also said that if he were to veto an energy project, he would only do so if the company’s environmental benefits outweigh the environmental risks of the pipeline construction.
The White House did not respond to a request for comment.
This is the second time in a week that the Trump administration has expressed concern over the Keystone.
On Monday, the administration sent a letter to Nebraska Gov.
Pete Ricketts, a Republican, saying that he was not able to meet the president’s pledge to build a pipeline that does not negatively impact Native American communities.
The administration also cited the pipeline’s projected impact on water resources and the possibility that it would create new threats to tribal sovereignty, as well as the possibility of creating new environmental hazards.
“Based on the ongoing review of the Dakota access project, the president is concerned that a construction of the Keystone would significantly exacerbate existing issues,” the letter said.
In an interview on “Fox & Friends” on Wednesday, Republican Sen. James Lankford of Oklahoma said the administration is trying to push the Keystone through without a full review of its environmental impacts.
“I don’t think it’s appropriate for us to make decisions like that without being fully briefed on what the impact of the new project would actually be,” Lankford said.
“This is a very important project and I hope that they make the best decision for our country.”
