None of the 108 board members of the U.S. Chamber of Commerce came forward to explicitly support the lobbying group’s policies on tobacco and climate change, according to a new report from a group of eight Senate Democrats, including Senator Elizabeth Warren and Senator Bernie Sanders.

The report, which was written by Senator Warren and Senator Sheldon Whitehouse, followed on reporting by The New York Times that revealed the chamber’s international campaign against antismoking laws and its efforts to undermine policies aimed at curbing global warming.

“The chamber’s lobbying is at odds with its own public positions,” the report found. It noted that the “organization strongly professes that it is anti-tobacco” and has claimed to support “efforts to reduce greenhouse gas emissions.”

In a statement, the chamber described the report’s contents as a “partisan line of attack” that was “egregiously false” and recycled “old myths and tired talking points.”
