Nope. This is a big big deal, actually. It's a bit complicated, but there is a statute called the enhanced whistle blower protection act. And the DOJ lawyers are the one's who would understand the intricacies better than anyone because they are the ones who normally have to investigate, defend and/or enforce the statute.
