64 percent of Trump‘s ambassadorial nominees so far have been white non-Hispanic males, a 7 percentage point increase from the eight years of the Obama administration. President Trump stands out from his six predecessors in his failure so far to nominate a single African-American female ambassador; African-American women made up 6 percent of all ambassadors under President Barack Obama and 5 percent under President George W. Bush, who had two African-American secretaries of state. Meanwhile, from September 2016 to June 2018, the share of African-Americans in the Senior Foreign Service—the top ranks from which most career ambassadorial nominees are drawn—dropped from 4.6 percent to 3.2 percent
