The Smithsonian has removed explicit reference to Donald Trump from an exhibit about impeached presidents.

The institution’s national museum of American history Washington, DC, made the change as part of an agreed review following White House pressure to remove an art museum director, the Washington Post reported.

On Thursday, a spokesperson for the museum said in a statement: “a future and updated exhibit will include all impeachments.”

Trump signed an executive order in March calling for “improper, divisive or anti-American ideology” to be removed from the museum and research institution, which is a premier exhibition space for US history and culture.

The order raised concern of political interference at the institution as well as fear that Mr Trump’s administration is undoing decades of social progress and undermining the acknowledgement of critical phases of American history.

“In September 2021, the museum installed a temporary label on content concerning the impeachments of Donald J Trump.

“It was intended to be a short-term measure to address current events at the time, however, the label remained in place until July 2025,” the spokesperson said in an email.

The Washington Post reported the exhibit now notes that “only three presidents have seriously faced removal.”

The temporary label read “case under redesign (history happens)” and also offered information about the impeachments of three former presidents.

The label reportedly detailed the impeachments of Andrew Johnson in 1868 and Bill Clinton in 1998, as well as Richard Nixon, who would have faced impeachment had he not resigned in 1974.

The spokesperson said that after a content review, the Smithsonian decided to restore the exhibit to how it looked in 2008.

A later statement from the museum said that “a future and updated exhibit will include all impeachments,” the Washington Post reported.

The Smithsonian receives most of its budget from the US Congress but is independent of the government in decision-making.

In June, Kim Sajet stepped down as director of the National Portrait Gallery, which is part of the Smithsonian, after facing criticism from Mr Trump.

Mr Trump became the first president to be impeached twice during his first term in office between 2017 and 2021.

The first impeachment came over accusations he pressured Ukraine to investigate Joe Biden and his son Hunter, and the second over the Jan 6, 2021, attack on the US Capitol by Trump supporters.

The other three US presidents impeached - or charged with misconduct - by the House of Representatives were acquitted by the Senate.
