The Smithsonian Institution on Saturday denied it was pressured by the Trump administration to remove a section of the National Museum of American History’s impeachment exhibit mentioning the two attempts to remove President Donald Trump from office.

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.

Last month, a placard referencing the impeachment of President Trump was reported to be missing from one of the museum's exhibits.
