In a Friday tweet, Customs and Border Patrol official Mark Morgan acknowledged that the agents were not wearing name badges. He said this was in order to protect them from retaliation.

[The director] said he doesn’t have his officers wear name tags because they’re being doxxed.

So yes, I as the acting commissioner have authorized and supported removing their names from their uniforms. Instead what we have though is a personal identifier. So we have that so we can identify. And we have each identifier associated with a specific name so we have all that information internally, and we’ll share that with the appropriate entities when it’s necessary.” ...
