Huma Abedins Cousins Convicted Of Fraud
Omar's brother, Irfan Amanat, was also convicted of securities fraud in 2018. Keepin it all in the family, I guess.

Omar was supposed to be sentenced in 04/2018. As of 08/01/2018, he wasn't. He's in jail as he's considered a flight risk.
After a cursory search, I can't find anything more on it.
