NEW YORK — Phil Gramm, a top adviser to presidential candidate John McCain, is resigning from the role as campaign co-chairman after his comments that the United States had become a “nation of whiners” who constantly complain about the state of the economy.

The former U.S. senator from Texas and past presidential candidate made the remarks earlier this month. McCain immediately distanced himself from the comments, but they have been criticized constantly as McCain tries to show he can help steer the country past its current financial troubles.

Gramm had also suggested that the country was facing a “mental recession” instead of real economic problems. Gramm said in a statement late Friday that he is stepping down as a co-chair of the campaign to “end this distraction.”
