The Trump administration has issued a list of seven words and phrases that the Centers for Disease Control and Prevention are "forbidden" from using in documents related to next year's budget, The Washington Post reported Friday.

The list of banned words includes: vulnerable, entitlement, diversity, transgender, fetus, evidence-based and science-based, according to The Washington Post report. In certain cases, alternative phrasing was offered. CDC employees were encouraged to use the phrase, "the CDC bases its recommendations on science in consideration with community standards and wishes," in place of "science-based" or "evidence-based" according to a source cited in The Washington Post report.

It is not clear why the Trump administration issued such a directive, but The Washington Post notes that other federal agencies, like Health and Human Services, have altered language addressing sexual orientation in its documentation since Trump took office.

The directive was met with an "incredulous" reaction when it was announced at a meeting Thursday with CDC employees, The Washington Post reported.

The White House has not released a response to The Washington Post report.
