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 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.

In a statement to CNN Thursday, The Smithsonian said the decision was made after a review of the museum’s “legacy content” this year.
