Upcoming 'upgrade' to Holocaust Museum exhibit on US response to Nazi Germany sparks some staff concerns: Sources

(WASHINGTON) -- An exhibit at the United States Holocaust Memorial Museum that takes a critical look at the United States' response to Nazi Germany is slated to temporarily close after Labor Day for upgrades, sparking concern among some staff over what potential changes could be made amid President Donald Trump's sweeping review of museums and their programming, sources tell ABC News.

The staff-wide email, sent after Trump signed an executive order in March directing federal agencies and the Smithsonian to eliminate what he called divisive and "anti-American" content from museums and national parks, informed staff that exhibit teams at the museum would work to "upgrade the gallery and the exhibition."

Sources tell ABC News that news that the temporary closure of the "Americans and the Holocaust" exhibit has increased concerns among some staffers who had been worried about the museums' direction under the new administration, after Trump in April fired and replaced five Democrats appointed to the board of the museum.
