Amid attacks from the White House, Smithsonian Secretary Lonnie Bunch is stepping down from his position after seven years of leading the Smithsonian Institution.

Lonnie G. Bunch III said Donald Trump’s attacks were not a factor in his decision.

After months of clashes with the White House, the historian and leader of the institution is retiring later this year.

Lonnie Bunch III, the Smithsonian's first black secretary, announced his intention to retire from the institution.

Lonnie Bunch says the decision has been made ‘with very mixed emotions’
