“I will not put my foot into the White House as long as Trump, [Vice President Mike] Pence, or [House Speaker Paul] Ryan (i.e., the possible succession of impeachments) will occupy it,” 2017 Nobel Prize winning physicist Joachim Frank told STAT in an interview, adding that he feels “very relieved” there’s no chance he’ll be meeting Trump at an event honoring American Nobel Prize winners at the Swedish embassy in Washington on Tuesday. “I cannot speak for the others; don’t know them personally yet, but I strongly believe that as thinking intelligent people they will have a similar attitude as I.”

Frank was among the 2017 Nobel Prize winners class for his work in chemistry, recognized for helping launch a medical imaging effort credited with making it easier to picture the biomolecular building blocks of life. He was awarded the Nobel in chemistry alongside the U.K.’s Richard Henderson and Switzerland’s Jacques Dubochet. At least one other Nobel Prize winner from this year told STAT they wouldn’t meet with Trump at a White House event even if invited.

This year, other than Frank, a trio of American scientists won the Nobel Prize in physics; three others won the Nobel Prize in physiology or medicine; and Richard Thaler won the Nobel Prize in economics.

Presidents have, with rare exception, met with Nobel Prize winners in events honoring them for the past two decades. On Tuesday, Michael Kratsios of the Office of Science and Technology Policy will attend the event honoring the American Nobel Laureates; most are expected to attend.

Trump’s position rejecting the theory of manmade climate change—endorsed by the overwhelming majority of the scientific community—and proposed funding cuts to science, public health, and biomedical research agencies has put him at odds with a number of prominent academics. Most notably, scientists across America orchestrated a “March for Science” to protest Trump administration policies in the spring.
