U.S. House Republicans filed a federal lawsuit on Monday against Attorney General Eric Holder, the country's top law enforcement official, seeking to obtain documents on a botched operation to link Arizona gun sales to Mexican drug cartels.

The suit likely means the debate over the anti-gun-trafficking operation nicknamed "Fast and Furious" will go on for months, lasting through the U.S. elections on November 6 when Democratic President Barack Obama is likely to face Republican challenger Mitt Romney.
