One, is not illegal to testify against a president when he has committed a crime. That is what the Impeachment was about, testifying about Monica was not Illegal, was not treason and you were comparing it, to say you weren't is the worse kind of hypocrisy, and BTW, you did not say anything about the press printing it, you were talking about someone testifying in front of the grand jury. Even so, if the paper revealed grand jury info then they are liable under the law.
The fact that we don't prosecute doesn't mean it isn't illegal.
Two, revealing Classified Information by printing it in a paper is as illegal as the person who released the info, PROVIDED the information hadn't become common knowledge before it was printed. In other words the papers who picked it up and reprinted the times story are not guilty, but the Times sure as hell is . Read the law, law and logic work just fine. It was, and is, illegal to commit treason, first amendment rights do not excuse the fact that they committed treason. What you are saying in effect, is that if someone in the goverment told me about a national secret, during war, I could blab it all over town, endangering lives,(Provided it was not released elsewhere first) and not be liable because my first amendment rights protect me simply because I was not the one who obtained the info originally. It doesn't work that way, and news agencies are not exempt from the law regardless of how you want to twist it.
#1 In the first case, the issue was not testifying against the President. It was the media's revealing what was said before a Grand Jury. Normally, revealing such information is illegal, but the media can, under the privileges of "higher law," ie: the Constitution, publish facts. It's call a "Free Press."
#2 Revealing classified information in a recognized publication is NOT illegal. You may not like it, but it is so. Please see comment above for clarification.
Please, as a very conservative retired reporter and lawyer, it's an issue I have dealt with a hundred times.
Was the NYT very wrong in publishing what they did? Yes.
Should Punch be punched? Yes.
Was it illegal under our system of constitutional law? No.
Please do not confuse what is right with hat is legal. They often have to relation to each other.
Kennedy's back seat bingo with teenagers in the Presidential limousine was very wrong, but not illegal.
