Yes, there in fact is. It's called obstruction of justice. One of the most fundamental and well-known laws regarding investigations.

8 U.S.C. § 1503 defines "obstruction of justice" as an act that "corruptly or by threats or force, or by any threatening letter or communication, influences, obstructs, or impedes, or endeavors to influence, obstruct, or impede, the due administration of justice."

1. I'm not arguing that Don Lemon is guilty of obstruction of justice - I am simply responding to your claim that there's nothing wrong with someone sharing information with the target of an investignation. This is simply not always the case, but in all fairness to you. It depends on the information being shared. It may be ok, it may not be. It depends on the information.

2. It's still early yet - He may eventually get charged if they determine he obstructed justice. However, him being a prominent, wealthy, gay black man and news personality with many powerful connections will make that *very* unlikely to occur.

3. If he does get charged - which I highly doubt - Just as I suspect will be the case with Smollett - it is doubtful he will serve a single day in jail and at the very most will likely get a small fine and probation.

The topic raised by you was whether Don Lemon or “anybody else” ( You very own words- not mine) would be breaking the law by sharing information regarding a police investigation with the target of that investigation. To which I answered “Yes, there in fact is” & then cited obstruction of justice & its definition. You were the one who imported others besides Don Lemon - not me. “there is no law he broke” He may not have, but that depends entirely on the information he shared - which makes your claim empty, speculative & outside the context of you initial response.
