The U.S. Chamber of Commerce and its affiliate pushing for limits on lawsuits doubled its lobbying spending to $135.5 million in 2012, newly released figures show.
The chamber and its Institute for Legal Reform reported spending $65.8 million in 2011.
The largest U.S. business lobby spent a record $144.2 million in 2009.
The group also spent $33 million on independent expenditures in the 2012 congressional elections, losing 36 of the 50 races where it ran campaign ads.
Since 1998, the chamber has spent close to $1 billion on lobbying, more than any other group, according to the Center for Responsive Politics, a Washington-based research group that tracks lobbying. That’s three times more than any other trade association, interest group or corporation.
