According to RapCurrent, Mohammed Gangat is a lawyer who specializes in overtime lawsuits, helping people who have gotten screwed over by their employers. He may be taking on another case though because he posted a video with none other than Sara Molina, where she expressed an interest in hiring him to get Tekashi to pay up.
When Gangat asked Molina what type of legal advice she needed, she laughed and said she could use some help getting child support payments on the regular. The clip is definitely a little weird with the lawyer recalling a time he commented on Sara's page, saying she looked "like a snack." That's certainly not the most professional thing to say to your potential clients but hey... I guess it worked.
