The Smithsonian said that it would update an exhibit at the National Museum of American History to reflect all impeachment proceedings in U.S. history after a placard was removed last month.

The museum's decision to remove a placard referring to President Donald Trump from an impeachment exhibit sparked concerns over Trump's influence on the cultural institution.

The Smithsonian removed references to President Trump's two impeachments from an exhibit on "Limits of Presidential Power," a Smithsonian spokesperson confirmed.
