A conservative-leaning independent political group is set to spend $6.1 million on a new television ad targeting President Barack Obama in eight states.

Americans for Prosperity announced Thursday that it would run the commercial in the battleground states of Colorado, Florida, Iowa, Michigan, Nevada, New Mexico, Ohio and Virginia. The ad suggests money from Obama's $814 billion economic stimulus package went to overseas green-energy companies.

Americans for Prosperity was founded by the billionaire oil industry brothers Charles and David Koch. The group spent $6.5 million earlier this year on ads criticizing Obama over Solyndra, a California-based solar energy company that went bankrupt despite a $535 million federal loan guarantee.
