According to the Washington Post, the museum has removed references to Trump's two impeachments from an exhibit.

The Smithsonian’s National Museum of American History in Washington, D.C., has removed references to President Donald Trump in a display about impeachments, despite Trump being the first and only president in American history to be impeached twice. But the museum says the move is temporary.

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