The Senate has voted to approve a $1 billion plan to cut spending for the Environmental Protection Agency and the Interior Department.
The measure, approved by a vote of 60-35, passed by a narrow margin, with the Republican majority supporting the measure.
Senate Majority Leader Mitch McConnell (R-Ky.) has said he wants to see the legislation enacted in the coming days.
The House of Representatives voted overwhelmingly to approve the bill, and the president signed it into law Tuesday.
The bill passed with little opposition.
It provides $7.8 billion for the EPA and $7 billion for its Office of Science.
It would reduce the agency’s budget by $1,200 million and $1 million for its workforce by $5 million each.
The White House has said it is considering eliminating funding for the office of science and technology policy and cutting the agency budget by 10 percent.
It also provides $3 billion for border security and border enforcement.
The Senate’s measure would also eliminate funding for programs that help states fight the spread of disease, including grants for vaccines and research to improve the vaccine.
The Interior Department is responsible for regulating the oil and gas industry.
The agency’s director, Sarah Shackleford, has been the subject of criticism for not doing enough to protect drinking water and the environment.
Shacklefield, who is from West Virginia, is the first woman to lead the agency since it was created in 1973.
