Here’s a report noting Schumer-Van Hollen’s potential impact on corporate anonymity for political spending.

U.S. companies would lose their ability to secretly finance political advertising run by organizations such as the U.S. Chamber of Commerce under a bill being considered by Democratic lawmakers.

The proposed legislation is a response to a Supreme Court ruling that allows corporations to spend unlimited amounts of their own money on political ads. The Jan. 21 decision triggered concern that companies would funnel unprecedented sums of cash into the Chamber’s decades-old system of anonymously funded pro- business campaigns.
