Unbelievable. US science is in a bad place.
We were asked to change language and delete data from a paper that already been through peer review successfully - "in order to comply with the Executive Order."

This is from the official journal of the US Surgeon General and the US Public Health Service.

So it happened. We have officially withdrawn a paper accepted for publication in a scientific journal because of editorial requests to remove language deemed out of compliance with executive orders.
