WATCH: Simple question about diversity trips up Sarah Sanders after Omarosa's departure

White House press secretary Sarah Huckabee Sanders was unable to answer a question related to former Trump administration aide Omarosa Manigault Newman.

Reporter Kristen Welker asked during a press briefing on Thursday how many senior staffers at the White House were African American following the departure of Manigault.

Sanders insisted the Trump administration was a "diverse team" of individuals and was intent on remaining that way.

But when asked for a specific number, Sanders was unable to answer.

According to The Washington Post, Manigualt's exit highlighted the "stark lack of diversity in Trump’s administration." Among Trump's Cabinet members and top staff, Ben Carson is the only remaining African American, the paper added.
