Jackie Robinson’s Legacy Vanishes, Then Reappears on Defense Department Site

An article on the Defense Department website devoted to Jackie Robinson’s military career disappeared and then reappeared, joining a series of government web pages on Black figures that have vanished under the Trump administration’s efforts to purge government websites of references to diversity and inclusion.

The brief biography describes Robinson’s childhood in California, his time in a segregated Army unit during World War II and his role in breaking baseball’s color barrier.

But for much of Wednesday, it displayed a “Page Not Found” message. When it reappeared Wednesday afternoon, there were no notable changes.

The discovery that the page had vanished generated significant backlash on Wednesday. “You can’t make this up!” Senator Tim Kaine, Democrat of Virginia, wrote on social media.

Representative Yvette Clark, a New York Democrat who represents the section of Brooklyn where Robinson once played, accused the Trump administration of erasing Black history.

“It doesn’t matter if his administration wants to walk back their attempt to censor” the page, Ms. Clark wrote on social media, “we know what they tried to do, and we’ll never forget it.”
