As someone who has had my press credentials denied by authoritarian China, I never thought I'd see this crap happen in the US. And this "most reporters are okay but @Acosta is aggressive" thing is the EXACT line Chinese propaganda printed about me. It's a tactic, people.
Right now, they're singling out @Acosta. But tomorrow it'll be Journalist X. And later Journalist Y and Z. It can happen very quickly. And of course, there's always something wrong with the reporter. They'll go back ten years to find something you misreported if they have to.
They'll start casting suspicion about not just your work, but your very character. All they need is a whiff of anything unsavory. And it'll be a talking point different people in the government will say, in public and private.
