"The letter - sent on Jan. 22, is currently at the FBI crime lab for analysis," reports ABC.
The Osundairo brothers agreed to cooperate with authorities after detectives confronted them with evidence that they bought the rope allegedly used in an attack that Smollett described to police as laced with racial and homophobic slurs at a Chicago hardware store, sources said. -ABC News
While Empire network Fox has thus far publicly stood by Smollett, TMZ reported on Tuesday that the star's screen time has been significantly reduced - with 9 scenes being cut to four, and Smollett "no longer the focus" of them.
Smollett reported in January that two white men physically assaulted him, yelling "this is MAGA country!" in addition to racist and homophobic slurs which were 'coincidentally' used in a play Smollett had done a reading for in New York City the day before, according to the Daily Mail.
Smollett says the men beat him up, poured a bleach-like liquid on him and wrapped a noose around his neck, before he was able to chase them off because the self-styled "gay Tupac" did not let his attackers win. Instead, he "fought the fuck back."
