Public Citizen's Chamber Watch and the Main Street Alliance examined the Chamber's spending in 35 House and Senate races using data from the Center for Responsive Politics. They found that as of Oct. 31, the Republican-leaning organization has spent $31.87 million in outside money on congressional contests.
The Chamber, which reportedly plans to spend $100 million in such races, has long been criticized by such groups for not disclosing its donors. As a 501(c)(6), the Chamber isn't required to disclose its donors.
