An investigation has been opened up by the US Attorney's Office with the support of the FBI, against the Clinton Foundation for allegedly engaging in corrupt activities. The US Attorney leading the investigation into the New York-based Clinton Foundation will be Preet Bharara, famously known for his aggressiveness in past prosecutions like CitiBank, organized crime including the Gotti crime family, insider trading cases like Raj Rajaratnam, scamster Bernie Madoff, and various elected New York officials, etc, etc.
To Indians, he became more famous for his pursuit of a case against Indian diplomat Devyani Khobragade.
Bharara has nailed some big fish - but unlike some of his high profile predecessors, Bharara doesn't have the political connections to vault himself someplace higher, like into politics like Giuliani, or to Washington like Comey. So as his tenure comes to an end, he's on his way out - but before he leaves, he'll probably pursue this one last case - which could now become the biggest case of his life. By successfully prosecuting this, he'll have made his biggest mark by bringing in his biggest fish, the Clintons. At a minimum, that will be his legacy. However, if he succeeds, he may reap political rewards that allow him to pursue a path into higher politics.
