The Trump administration marginalized the role of science in policy making, halted numerous research projects, and saw the departure of scientists who said their work was marginalized or suppressed. It was the first administration since 1941 not to name a Science Advisor to the President. In July 2018, Trump nominated meteorologist Kelvin Droegemeier for the position, and Droegemeier was confirmed by the Senate on January 2, 2019, the final day of the 115th United States Congress. He was sworn in by Vice President Mike Pence on February 11, 2019. While preparing for talks with Kim Jong-un, the White House did so without the assistance of a White House science adviser or senior counselor trained in nuclear physics. The position of chief scientist in the State Department or the Department of Agriculture was not filled. The administration nominated Sam Clovis to be chief scientist in the United States Department of Agriculture, but he had no scientific background and the White House later withdrew the nomination. The United States Department of the Interior, the National Oceanic and Atmospheric Administration, and the Food and Drug Administration disbanded advisory committees.
