This Congress is the most diverse ever. But Hill staffers remain overwhelmingly white.

The 117th Congress is the most diverse ever, with the largest representation of racial and ethnic groups in history, a 97 percent increase over the last ten Congresses, according to the Pew Research Center. But among Hill staffers like Brewer — the people who really run Congress on a working level — there’s a dearth of diversity.

Despite efforts to diversify the Hill over the last several years, the racial makeup of House and Senate staffs don’t align with their districts and voting bases. Among top-level staffers, the lack of diversity is most striking: there is only one Black chief of staff in the Senate and only four Latinos. Warnock’s chief of staff, for example, is white.
