"Chatwal went to great lengths to undermine both election laws and our system of justice. Today's guilty plea shows our vigilance and determination to prosecute those who damage the integrity of elections by masking the true sources of campaign contributions," O'Neil said.
"Chatwal's scheme sought to subvert the very purpose of the Election Act. Chatwal then rolled the dice to stymie the government's investigation, thinking he could corruptly convince witnesses to his federal election crimes to stay silent. That gamble did not pay off," said US Attorney Loretta Lynch.
The Washington Post said Chatwal faces a maximum of nearly six years in prison when he is sentenced on July 31. He is free on a USD 750,000 bond secured by property in Manhattan.
A spokesman for Chatwal said he "deeply regrets his actions and accepts full responsibility for the consequences."
Chatwal was awarded Padma Bhushan in 2010 for his role in the historic India-US civilian nuclear deal. He heads the chain of the upscale Hampshire Hotels.
