Hinting that media cover or not cover any story is so far beyond the purview of the TSA that no competent journalist would consider taking them seriously, making this a comparatively mild nightmare.
The Supreme Court can't "slap them" for anything; someone with standing would have to bring a case, and for that case to have merit, some journalistic outlet would have had to have its discretion actually impinged by the TSA.
There might be a suit brought on behalf of one of these reporters and/or their employer arguing that the implication of consequences from such a powerful entity without a court order constitutes illegal interference with their business, possibly entitling them to some damages, and more importantly, establishing some very important precedent which might prevent the TSA from ever attempting such a stunt in the future. I could certainly see many lawyers salivating at the prospect of winning a suit against such a well-funded target, not to mention the notoriety such a contentious issue would bring them in any event.
Maybe you're not familiar with the Federal Tort Claims Act, which provides a waiver for the federal government's immunity in the case that a federal employee has been shown to have caused wrongful damage.
