The Pentagon has faced questions from lawmakers, local leaders and citizens over the removal of military heroes and historic mentions from Defense Department websites and social media pages.

In response, the department has scrambled to restore a handful of those posts as their removals have come to light. While the pages of some well-known veterans, including baseball and civil rights icon Jackie Robinson, are now back up on Pentagon websites, officials warn that many posts tagged for removal in error may be gone forever.

The restoration process has been so hit or miss that even groups that the administration has said are protected, like the Tuskegee Airmen, the first Black military pilots who served in a segregated World War II unit, still have deleted pages that as of Saturday had not been restored.

This past week chief, Pentagon spokesman Sean Parnell said in a video that mistaken removals will be quickly rectified. “History is not DEI,” he said, referring to diversity, equity and inclusion.
