…you can’t call for Rubio and the others to be jailed and avoid the reporter.

I'm not calling for them to be jailed - I'm pointing out that under your interpretation of the statutes, they've committed a crime.

And no, the reporter is in a different factual position. The others deliberately and intentionally engaged in a work discussion involving national security on an unsecured channel. The argument that was raised against Clinton is an allegation that she knew, or should have known, that if she conducted work on an unsecured platform that there was a likelihood that classified information would end up there. The same would apply to the other government participants in this chat, since they also deliberately and intentionally discussed national security issues on Signal. But not Goldberg, who was placed into the channel without his consent or knowledge and did not participate in the discussion.
