What Are Congress Members Trading?

I am quoted in this U.S. News & World Report article:

David Kass, clinical professor of finance at the University of Maryland, Robert H. Smith School of Business, says, “Since members of Congress do have access to inside information such as the outlook for the overall economy, specific industries, and individual companies, large transactions on either the buy side or the sell side might serve as a useful signal as to major changes that could be forthcoming that could affect the securities involved.”
