"It is a matter of immense pride and satisfaction for all the women in the world and in particular, women in democratic electoral politics that you have become the first woman to be a candidate of one of the two major political parties in the United States for the Presidency," she said.
In a letter to Clinton, Jayalalithaa said the former Secretary of State, while "creating history," had given voice and hope to the cause of women empowerment across the world.
"My best wishes are with you for the further stages of the campaign and for the Presidential Election in November this year. I have no doubt that as your political career peaks, you will continue to be a role model for women across the world," she told the Presidential hopeful.
