Starbucks Corp chief executive Howard Schultz urged members of the public on Friday to join a novel campaign he launched last month seeking to break partisan gridlock in Washington and spur economic growth.

In an open letter circulated via email, the head of the world's biggest coffee chain invited concerned Americans to take part in a national call-in conversation next Tuesday hosted by the nonpartisan group No Labels, dedicated to fostering cooperative and more effective government.

Like so many of you, I am deeply disappointed by the pervasive failure of leadership in Washington, Schultz wrote in a letter addressed: Dear Starbucks Friend and Fellow Citizen.

Last month, Schultz made headlines when he called on business leaders to pledge to withhold campaign contributions to incumbent lawmakers on Capitol Hill until they reached a bipartisan deal on the national debt. He also challenged those executives to do their part by hiring workers to give the national economy a much-needed jolt.

He has said that more than 100 U.S. business executives have since signed on to his pledge.
