Applauding the Indian American community for its role in strengthening the bilateral ties, Republican Presidential nominee John McCain has acknowledged its "excellent work" in the advancement of the Indo-US nuclear deal through "overwhelming bipartisan support" in Congress.

"The Indian American community is an integral part of the modern American tapestry. You have contributed greatly to strengthening the relationship between the US and India.

"The most recent example of your excellent work was the advancement of US-India civil nuclear cooperation through overwhelming bipartisan support in our Congress," McCain said in a 'Thank You Letter' on establishment of 'Indo-Americans for McCain Coalition.'

He said the community's "efforts and commitment will help our campaign uphold the principles of smaller government, a strong national defence and lower taxes for working Americans."

"I am truly appreciative. Through the Indo-Americans for McCain Coalition, you have shown a strong commitment to building a grassroots network of supporters to ensure victory in (the) November Presidential poll)," McCain said in the letter released by the Convener/Coordinator of the new organisation, Deven Verma.

Stating that there are many challenges ahead, the Republican White House hopeful said "I welcome your input as we address them."

"I intend to work closely with you to ensure that the concerns of Indian Americans and the Indo-American community as a whole are reflected in my campaign," the Arizona Senator said.
