Aam Admi Party claimed Arvind Kerjriwal is asked to be Modi's replacement.
Activist-turned politician Arvind Kejriwal and Manipal Group chairman Mohandas Pai are two new faces who will address the prestigious Wharton India Economic Forum meeting.
The Wharton India Economic Forum revoked its decision to invite Gujarat Chief Minister Narendra Modi to deliver a keynote address after three Indian-American professors from the University of Pennsylvania sent a petition signed by about 135 people "furious" against such a move.
'It's been overwhelming to see such generous and warm responses,' Pichai tweeted.
The organization headed by Mallika Dutt, its founder and president, received $125,000 (Rs 75 lakh) and an official recognition at an award ceremony on April 24 at the University of Pennsylvania.
