The U.S. Chamber of Commerce more than doubled its spending on lobbying efforts in 2012, according to disclosure records.
The business lobby spent more than $135 million last year, with the U.S. Chamber of Commerce spending $103.9 million and the Chamber's Institute For Legal Reform doling out $31.6 million towards the effort.
The Chamber and its legal arm spent more than $40 million during the fourth quarter. That figure includes what was spent on campaign ads during the election cycle.
Last year, Chamber lobbyists worked on a number of varying issues, including the Dodd-Frank law implementation, online gaming, and the Environmental Protection Agency's broiler rule.
In 2011, the Chamber and the Institute for Legal Reform spent $65 million on lobbying efforts.
