A prominent staff member at the United States Holocaust Memorial Museum is urging the Trump administration to admit all immigrants from “violence-stricken countries”—which potentially could mean taking in hundreds of millions of people from around the world.

In the Washington Post’s online edition this week, Rebecca Erbelding, a staff historian at the museum who is often quoted as one of its spokespeople, wrote: “The overriding American priority should be admitting refugees from violence-stricken countries, and sooner rather than later — a lesson of the Holocaust that Trump is ignoring. “

During his final year in office, President Barack Obama authorized the admission of 110,000 refugees annually. President Donald Trump admitted 53,000 last year.

U.S. law defines a refugee as someone who has “a well-founded fear of persecution based on religion, political opinion, race, nationality, or membership in a particular social group.”

There is no category for people coming from countries that are “violence-stricken.” There are so many countries that can be described as having substantial violence in their societies, that the number of immigrants to America could reach into the hundreds of millions under Erbelding’s formula.

The Hatch Act of 1939 restricts the public political activities of employees of U.S. government institutions, such as the Holocaust Museum. A federal employee “may not use email or social media to engage in political activity,” and “may not engage in political activity while on duty.” In addition, the U.S. Department of Justice website states that a government employee should not use his or her “position or title…to give the appearance of governmental sanction.”

Erbelding’s op-ed in the Washington Post this week did not identify her position at the Museum. However, as a prominent museum staff member and as one of the curators of its latest exhibit, “Americans and the Holocaust,” Erbelding has been a high-profile spokesperson to the news media on behalf of the museum, including in a recent feature story in the Washington Post itself.
