Whistleblower protections pertain to covered disclosures of wrongdoing to colleagues, the Congress, supervisors, the IG, DOJ, etc. I am guessing that disclosures to paid hacks like this lawyer expose you and your information while not giving you the protection you need because a paid for disclosure is not a protected disclosure AND it undermines your credibility. You did it for the money.
In my best French this jerk is a sheister Ass4ole. But that's redundant. He is a swamp-dwelling attorney.
PS He called himself a lobbyist, so little more need be said.
