The Devyani Khobragade case came upfor a discussion at Harvard Law School with India-born US prosecutor Preet Bharara telling the graduating class that the"intense" criticism and accusation hurled at him for charging the Indian diplomat with visa fraud had upset him.

Bharara was invited to address students and faculty at the prestigious law school on its 2014 Class Day ceremony last week

The top US attorney in Manhattan spoke about the criticism he faces from all quarters as well as from various governments because of his work.        He added that he has even "been banned from Russia".

Raising the Khobragade case, Bharara said he got the most flak for prosecuting the former Indian deputy counsul general even though the case was initiated and investigated by the US state department and seasoned law enforcements officials.

"You may have heard about the case we brought last year in which the state department arrested a mid-level Indian female diplomat Devyani Khobragade for visa fraud in connection with lies about what she would ultimately pay her domestic worker (also an Indian)."
