Feds probing whether Smollett played a role in sending threatening letter he received

The FBI and the US Postal Inspection Service are currently investigating whether Jussie Smollett played a role in sending a threatening letter addressed to him at “Empire’s” Chicago studio prior to the alleged attack, two federal officials confirm to ABC News.

The accusation, made by the two brothers who were persons of interest, has not been confirmed.

The letter, which was sent Jan. 22, is currently in the FBI crime lab for analysis, one of the sources said.
