...An archived version of the Arlington National Cemetery website's "prominent military figures" page from late February 2025 displayed Powell's biography beginning with the sentence, "General Colin Powell, a Vietnam veteran, was the first African American to hold three of the U.S. government's highest positions: national security adviser (1987-1989), chairman of the Joint Chiefs of Staff (1989-1993), and secretary of state (2001-2005)."

By early March, another archived version of the page confirmed the removal of the fact that Powell was the first African American to hold the three positions. Sometime between March 17 and 21, one or more people restored the sentence to the page.

Hesketh probably had little or nothing to do with it; somebody was following Trump's directive to remove anything that looked "inclusive" from dot-gov web pages.
