DES MOINES, Iowa — A group supporting Mitt Romney is spending more than $10 million on a new television advertisement criticizing President Barack Obama's handling of the economy.

The ad from the group Restore Our Future tells viewers there are even more Americans without work this month. And it criticizes Obama for joking about the economy and suggesting that his plans have worked.

The spot will air for more than a week across 11 presidential battleground states, including Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin.

Political strategists with close ties to Romney work for Restore Our Future, a super PAC that can accept unlimited donations, but cannot coordinate directly with the Republican's presidential campaign.

The new ad represents the single largest investment from the group this election.
