This actually IS criminal behavior

Former Director of National Intelligence James Clapper allegedly leaked information to CNN early last year regarding the classified briefings given to then President-Elect Donald Trump and President Barack Obama on the salacious dossier claiming the Russians had compromising information on the president-elect, according to government sources, who noted the evidence of the leak was collected during the House Intelligence Committee’s Russia investigation.

Now the committee report is only alleging that Clapper is responsible for the leaks, but it certainly makes sense based on what we currently know of Clapper. How much of the committee's evidence is solid vs circumstantial evidence remains to be seen.

The truth is that without the leaks to CNN from someone within the intelligence community, we probably would have heard very little about the Steele dossier. According to most media sources, the initial reaction to the dossier was not to write about it, as it was basically unsubstantiated. But when a source from the upper levels of the intelligence community lends it credibility by suggesting to the media that it was being investigated, then it becomes real news.

Clapper had just gotten a pass for possible perjury charges from lies told during congressional hearings back in 2013. The DOJ allowed the statute of limitations run out just a few days ago. So one has to think if there is solid enough evidence that he is the one that leaked to CNN (his current employer) that he would face charges for it. Certainly, letting him off again without charges for this sort of behavior would be a problem.
