"I want to congratulate President Mukherjee on his swearing-in as the 13th President of India. President Mukherjee has been a strong partner to America and the American people, working throughout his career to deepen our cooperation on a wide range of issues," Clinton said in a statement.
"I look forward to continuing to work with the government and people of India. Together we will build on our shared democratic values, strengthen this relationship even more and create a brighter future for both our people," said Clinton, who maintained a close relationship with Mukherjee.
In the last three and half years, Clinton met Mukherjee almost every time the Indian leader visited Washington.
