X is discouraging users from viewing a link to an NPR story about Donald Trump’s recent visit to Arlington National Cemetery, raising questions about whether the Elon Musk-owned platform is putting its thumb on the scale for the former president.

On Thursday, NPR reporter Stephen Fowler posted a link to a story in which he quoted an Army official who said that an employee at Arlington National Cemetery was “abruptly pushed aside” during an event attended by Trump and members of his campaign earlier this week. The outlet had previously reported that there was a “physical altercation” at the event with campaign staff over federal laws barring campaign activities at the cemetery.

Some users on X who attempt to click a link to the story are greeted with a warning message saying that X has deemed that “this link may be unsafe.” It states that it could be malicious, violent, spammy or otherwise violate the platform’s rules, but doesn’t explain why the link was flagged. Fowler posted a thread on X, each tweet of which contained a link to his story — the warning appears to affect the first two instances of the link but not others, for reasons unknown. It’s highly unusual for such a warning to appear before a link to a mainstream website. Other links to NPR, as well as other coverage of Trump’s visit to Arlington, don’t appear to have such a label.

Notably, Musk has been a vocal supporter of Trump this election, and recently held a lengthy live streamed conversation with him on X. Musk has also publicly feuded with NPR in the past, adding a “state affiliated media” label to its account for several months last year. NPR hasn’t posted from its main account on X since the label was added last April.

X didn’t immediately respond to questions about its use of the label.
