According to Donald Trump, what aspect of history does the Smithsonian focus on too much?

Donald Trump has expressed the viewpoint that the Smithsonian emphasizes the negative aspects of slavery to an excessive degree, asserting that this focus skews the narrative of American history. By highlighting how negative portrayals of slavery overshadow other historical contexts, his argument suggests a desire for a more balanced perspective that includes positive contributions and achievements, rather than a narrative that solely dwells on the horrors of slavery. This emphasis on the severity of slavery's impact, especially in institutions like the Smithsonian, raises concerns for him about potentially misrepresenting the full scope of American history and culture.

In this context, the other options, while related to significant historical themes, do not directly align with Trump's specific critique of historical portrayal by institutions. For instance, discussions of economic impact or cultural contributions encompass broader facets of history that may not connect directly with his focus on the narrative surrounding the severity of slavery.
