It's bad enough that there's a law on the books that allows the US government to go after American journalists, but in this case, the US government is asserting the right to prosecute a foreign journalist who operated from outside the US. As far as I understand it, if Julian Assange is extradited, he will not be able to argue in court that WikiLeaks' publications were in the public interest.
Good luck getting the Supreme Court agreeing with that. That greatest disappointment in the entire American Experiment has to be the US Supreme Court.
That was the founders greatest mistake, vesting soo much power in this single branch
They made up their own powers. There's nothing about judicial review in the Constitution. They basically decided that they had that power, and everybody else agreed with them.

So perhaps their greatest mistake wasn't vesting too much, but vesting too little. That left the court open to write its own job description. And also to create lifetime appointments, in theory to de-politicize it, but in practice to enshrine ideologies for many decades.
That said, whistleblower protection rarely covers confidential information anyway.
