According to Clinton, a major benefit to the country's bid is that all U.S. host cities already have existing stadium and transportation infrastructure necessary to host games.
"That means that if we get the (World Cup) there will be an economic stimulus estimated between $400-$600 million per host city," he said at a news conference to announce his role as honorary chairman of the U.S. bid.
"That will be very good for a lot of families that are still hurting, a lot of communities that are still digging out from under the current economic crisis."
News of Clinton's involvement comes after a weekend where England's bid chief stood down following a newspaper report that he made bribery allegations against rival bidders.
"Hosting another World Cup in the United States where about 12 percent of the population is foreign born will ensure high attendance for every match played because we will have lots of fans for every team that shows up," he said.
The hosts of the 2018 and 2022 World Cup will be decided at a meeting of FIFA's executive committee in December.
